INTRODUCTION
Bhagavad Gita  (2.29) says
    aashcharyavat  pashyati kashchid enam aashcharyavad vadati tathaiva chaanyah
    aashcharyavacchainam  anyah shrinoti shrutwaapyenam veda na chaiva kaschit // 
  Some look on the  Self as a wonder; some speak of It as a wonder; some hear of It as a wonder;  still others, though  hearing, do not  understand It at all.
The Self is  incomprehensible because it is not known by the ordinary means of knowledge.  Though the knowledge of the Self is freely accessible to all mankind, it is  attained only by a very few who are willing to pay the price in the form of  self-discipline, steadfastness and non-attachment. Though the truth is open to  all, many do not feel any urge to seek. Of those who have the urge, many suffer  from doubt and vacillation. Even if they do not have doubts, many are scared  away by difficulties. Only a few rare souls succeed in braving the perils and  reaching the goal. 
Although it is  difficult to comprehend the idea of the Self, if one starts the practice of  listening (sravanam), continuous reflection (mananam) and long  contemplation (nidhidhyasan) it is possible to realize the Self in him.
THE  TEXT
Mantra 1
    
    svabhāvam eke kavayo vadanti kālaṃ tathānye parimuhyamānāḥ / 
    devasyaiṣa mahimā tu loke yenedaṃ bhrāmyate brahmacakram // 6.1  // 
Some learned  men speak of the inherent nature of things and some speak of time, as the cause  of the universe. They all, indeed, are deluded. It is the greatness of the  self-luminous Lord that causes the Wheel of Brahman to revolve. 
Svetasvatara  Upanishad discusses the same idea of the Gita as stated above in this Mantra.  At the beginning in Chapter 1.2 this same question was raised and many answers  like the nature of things, time etc., were proposed and rejected.  After meditation it was concluded that it was  Brahman by His own power, daivatma sakti, by His own maya, created this  universe.
Here again the  Upanishad goes back to the same question and states that some scholars say the  root cause of the world is its inherent  nature of things or the natural potency of its  objects and some others opine it is the element of time that is the cause of  this world. But all of them are wrong. The universe is not a self-creating,  self-evolving, self-destroying entity. It is lifeless and inert. Brahman is the  ultimate cause of the world process which has been described as Brahmachakra, the Wheel of Brahman in Chapter 1.4.
GREATNESS OF THE LORD
Mantra 2
yenāvṛtaṃ nityam idaṃ hi sarvaṃ jñaḥ kālakālo guṇī sarvavidyaḥ / 
    teneśitaṃ karma vivartate ha pṛthivyāptejo'nilakhāni cintyam //  6.2 //  
He by whom  the whole universe is constantly pervaded, who is the knowledge itself,  the Author of time who is sinless and  omniscient, at whose command the work which is called earth, water, fire, air  and akasa appears as the universe, on Him the wise  should reflect upon.
The Lord is  described as He who
•Pervades  the entire universe
•Is  the very stuff of consciousness
•Is  the controller of time, the destroyer of all material entities
•Is  endowed with three gunas because of His association with maya power
•Is  all-knowing and 
•Appears  as the five elements (in the sense the five elements are super-imposed on Him) because  of which He seems to be the universe which remains under His control.
The idea is that  we should remember that Brahman is behind this universe and accordingly fix our  mind on that reality and meditate.
Mantra 3
tat karma kṛtvā vinivartya bhūyas tattvasya  tattvena sametya yogam / 
    ekena dvābhyāṃ tribhir aṣṭabhir vā kālena caivātmaguṇaiś ca sūkṣmaiḥ // 6.3 // 
The yogi who  first performs actions and then turns away from them and who practises one,  two, three, or eight disciplines, unites one principle with another principle  and with the help of virtues cultivated by the self and of subtle tendencies  attains Liberation in course of time.
The nature of  Perfect Knowledge and the disciplines required to be practiced for achieving it  are now discussed. 
The seeker, referred to here as the Yogi, performs all his  actions as offerings to the Lord thus making his heart pure. When a man  performs his duties, regarding himself as an instrument of the Lord and  surrendering all the fruits to Him, he is said to renounce all his duties or  the sense of duty drops away from him. Thus he becomes entitled to the life of  a sanyasi fully understanding that the idea of duty is the result of  attachment.
The one, two, three or eight duties referred to in the Mantra  mean service to the Guru, love of God, sravana, manana, nidhidhyasana of  scriptures and ashtanga yoga stipulated in Patanjali Yoga sutras.  Uniting one principle with another principle means understanding and  experiencing the essence of the mahavakya “Tatvam Asi’. The aspirant who  practices these disciplines and who cultivates virtues like charity, purity,  desirelessness, freedom from malice etc., attains liberation or kaivalya.
Mantra 4
ārabhya karmāṇi guṇānvitāni bhāvāṃś ca sarvān viniyojayed yaḥ / 
    teṣām abhāve kṛtakarmanāśaḥ karmakṣaye yāti sa tattvato 'nyaḥ // 6.4 //  
He who  attains purity of heart by performing actions as an offering to the Lord and  merges prakriti and all its effects in Brahman, realizes his true Self and  thereby transcends phenomena. In the absence of maya, both collective and  individual, all his past actions are destroyed. After the destruction of the  prarabdha karma he attains final Liberation. 
This Mantra can  be divided into two sections for a better understanding. The first section  reads as “He who attains purity of heart by performing actions as an offering  to the Lord and merges prakriti and all its effects in Brahman, realizes his  true Self and thereby transcends phenomena”. 
This is the  concept of Karmayoga as taught in the Bhagavad Gita 9.27 and 28 and 5.10 and  11. A man should perform his duties regarding himself as the God’s instrument  and surrendering the results to Him. Thus the impurities of his heart are  destroyed and he is qualified for the higher disciplines of meditation and  Samadhi. Such a man of meditation sees the universe in Brahman. How? In  Vedanta, the effect is merely a name and it has no existence independent of the  cause, which alone is real. For instance, a pot is made out of clay. The pot is  therefore the effect and the clay is the cause. What makes the pot different is  its shape and name; yet it is not something other than clay. It is just clay in  a different form and hence the real thing is clay only. What the Mantra says is  that a wise man sees the effect in the cause which is referred to as merging of  prakriti and its effects in Brahman that is to say for him the universe is  non-different from Brahman, the causeless cause.
The second  section reads “In the absence of maya, both collective and individual, all his  past actions are destroyed. After the destruction of the prarabdha karma he  attains final Liberation”.
The notion of  non-duality i.e., action, actor and results belongs to the realm of maya. When  maya is destroyed the vasanas created by past actions or karma and the resultant  bondages are also destroyed (Bhagavad Gita 4.37). In Vedanta everybody has to  reap the consequences of his past actions. The results of those actions which  have already begun to bear their fruit (i.e. the cause for the present birth  itself) must anyway have to be undergone. This is called prarabdha karma.  When this karma which is bearing fruit gets completely exhausted the wise man,  who has gone beyond maya or prakriti, attains liberation or mukti or  freedom from the cycle of births and deaths.
Mantra 5
ādiḥ sa saṃyoganimittahetuḥ paras trikālād akalo 'pi dṛṣṭaḥ / 
    taṃ viśvarūpaṃ bhavabhūtam īḍyaṃ devaṃ svacittastham upāsya pūrvam //  6.5 //  
The Great  Lord is the beginning, the cause which unites the soul with the body; He is  above the three kinds of time and is seen to be without parts. After having  worshipped that adorable God dwelling in the heart, who is of many forms and is  the true source of all things, man attains final Liberation.
An attempt to  describe Brahman, the Lord continues in these Mantras, however much such  efforts are futile. He is the primal cause of all beings and things. The soul  through avidya, becomes united with the body and the Lord is the cause of such  avidya, which manifests as both good and evil. Attachment to good and evil is  the cause of the embodiment. Thus the Lord, Brahman, is responsible for the  good as well as the evil activities.
He is beyond the  three times - past, present and future. We cannot specify when he existed or  when he will exist because he always exists, above time. He is without parts  means that he is not made up of something. He is not a composite object just  like bones, tissues, blood etc which make up our bodies. Brahman is without  such parts and he is undifferentiated.
He is of many  forms because he is everything. He is the cause of existence. All things exist  because he exists and without him nothing can exist. All forms are his forms.
The mantra  advises that that the seeker should meditate on Paramatman who is within his  own heart when he will realize that there is no more “He’ and ‘I’. His own  identity merges with that of object of meditation and he becomes completely  dissolved, as it were, in Brahman. He no longer exists. There is only Brahman.
Mantra 6
sa vṛkṣakālākṛtibhiḥ paro 'nyo yasmāt prapañcaḥ parivartate 'yaṃ / 
    dharmāvahaṃ pāpanudaṃ bhageśaṃ jñātvātmastham amṛtaṃ viśvadhāma // 6.6 // 
He from whom  this universe proceeds is higher and other than all forms of the Tree of the  World and of time. When one knows Him who is the indweller, the bringer of  good, the destroyer of evil, the Lord of powers, the immortal support of all,  one attains final Liberation. 
The Lord is  described as the One other than the tree of the world and of time. As in the  Bhagavad Gita (15.1), here also the world is compared to a tree which means  that which does not exist permanently. Within the Lord the world keeps going in  and coming out. He supports virtue and destroys vice, the source of all and the  supporter of the world. He is immortal and the inmost Self of all. If one knows  Him as his own Self he attains liberation.
Mantra 7
tam īśvarāṇāṃ paramaṃ maheśvaraṃ taṃ devatānāṃ paramaṃ ca daivataṃ / 
    patiṃ patīnāṃ paramaṃ parastād vidāma devaṃ bhuvaneśam īḍyam // 6.7 //  
We know Him  who is the Supreme Lord of lords, the Supreme Deity of deities, the Ruler of  rulers; who is higher than the imperishable prakriti and is the self-luminous,  adorable Lord of the world. 
All these  adjectives are used to emphasize the uniqueness of Brahman. He is the supreme  among all gods. He is self-luminous and the God of all gods, the Ruler of all  the rulers. He is higher than Brahma. He rules the world and is the sole object  of worship in the world. He is to be known as our own self.
Mantra 8
na tasya kāryaṃ karaṇaṃ ca vidyate na tatsamaś  cābhyadhikaś ca dṛśyate / 
    parāsya śaktir vividhaiva śrūyate svābhāvikī jñānabalakriyā  ca // 6.8 // 
He is without  a body or organs; none like unto Him is seen, or better than He. The Vedas  speak of His exalted power, which is innate and capable of producing diverse  effects and also of His omniscience and might. 
The Lord has no  body or organs. None is His equal and none is His superior either. He possesses  all powers of knowledge and action which are natural to Him. This has been  confirmed by the scriptures.
Mantra 9
na tasya kaścit patir asti loke na ceśitā naiva ca tasya liṅgaṃ / 
    sa kāraṇaṃ karaṇādhipādhipo na cāsya kaścij  janitā na cādhipaḥ // 6.9 // 
He has no  master in the world, no ruler, nor is there even a sign of Him by which He can  be inferred. He is the cause, the Lord of the lord of the organs; and He is  without progenitor or controller. 
There is none in  this world who is His master or who governs Him and there is nothing by which  He can be identified. He is the cause of all. He is also the Lord of the jiva  who is the lord of all the sense-organs. None is His creator and none is His  controller.
Mantra 10
yas tantunābha iva tantubhiḥ pradhānajaiḥ svabhāvataḥ / 
    deva ekaḥ svam āvṛṇoti sa no dadhād brahmāpyayam //  6.10 // 
May the non-dual  Lord, who, by the power of His maya, covered Himself, like a spider, with  threads drawn from primal matter, merge us in Brahman! 
As a spider  hides itself by its own web, the Lord hides Himself effortlessly within the  projections of his maya such as names, forms and actions. May He kindly unite  us with Brahman?
Mantra 11
eko devaḥ sarvabhūteṣu gūḍhaḥ sarvavyāpī sarvabhūtāntarātmā / 
    karmādhyakṣaḥ sarvabhūtādhivāsaḥ sākṣī cetā kevalo nirguṇaś ca // 6.11 // 
The non-dual  and resplendent Lord is hidden in all beings. All-pervading, the inmost Self of  all creatures, the impeller to actions, abiding in all things, He is the Witness,  the Animator and the Absolute, free from gunas. 
He is the one  without a second, yet he is hidden in every being. He is all pervasive, the  Self of all. He gives to all beings the fruits of their actions, and he is the  support of all. He is the witness, bestower of consciousness, without  attributes and unconditioned.
Bhagvad Gita  says
    upadrashtaanumantaa cha bhartaa bhoktaa maheshwarah
    paramaatmeti chaapyukto dehe'smin purushah parah // 13.23 //
  The Supreme Purusha in this body  is also called the Witness, the Approver, the Supporter, the Experiencer, the  Sovereign Lord and the Supreme Self.
Mantra 12
eko vaśī niṣkriyāṇāṃ bahūṇām ekaṃ bījaṃ bahudhā yaḥ karoti / 
    tam ātmasthaṃ ye 'nupaśyanti dhīrās teṣāṃ sukhaṃ śāśvataṃ netareṣāṃ // 6.12 // 
There is a  non-dual Ruler of the actionless many; He makes the one seed manifold. Eternal  happiness belongs to the wise, who perceive Him within themselves-and not to  others.
He is non-dual;  he controls everything and makes one seed to breed many seeds. Wise people see  such a Lord in themselves and attain liberation but not others.
Mantra 13
nityo nityānāṃ cetanaś cetanānām eko bahūnāṃ yo vidadhāti kāmān / 
    tat kāraṇaṃ sāṃkhyayogādhigamyaṃ jñātvā devaṃ mucyate sarvapāśaiḥ // 6.13 // 
He is the  Eternal among the eternal, the Conscious among the conscious and though non-dual,  fulfils the desires of many. He who has known Him, the luminous Lord, the Great  Cause, to be realized by Knowledge (Samkhya) and yoga, is freed from all  fetters. 
The Lord gives  eternity to all the eternals, consciousness to those who are conscious. He is  alone, yet he is able to fulfill the wishes of all. You realize him only  through knowledge and when you have this realization, you become free from  ignorance.
Mantra 14
na tatra sūryo bhāti na candratārakaṃ nemā vidyuto bhānti kuto 'yam  agniḥ / 
    tam eva bhāntam anubhāti sarvaṃ tasya bhāsā sarvam idaṃ vibhāti // 6.14 // 
The sun does  not shine there, nor the moon and the stars, nor these lightnings-much less  this fire. He shining, everything shines after Him. By his light all this is  lighted. 
The sun, moon  and the other luminous things derive their light from Brahman and without  Brahman they cannot give any light. Brahman is the source and goal of  everything. 
This Mantra  occurs in Kathopanishad (2.2.15), Mundaka Upanishad (2.2.10) and Bhagavad Gita (15.6).
Mantra 15
eko haṃso bhuvanasyāsya madhye sa  evāgniḥ salile saṃniviṣṭaḥ / 
    tam eva viditvāti mṛtyum  eti nānyaḥ panthā vidyate 'yanāya // 6.15  // 
In this  universe the Swan, the Supreme Self alone exists. It is He who, as fire, abides  in the water. Only by knowing Him does one pass over death, there is no other  way to reach the Supreme Goal. 
The supreme  Self, Brahman, is referred to as the swan which means the destroyer of  ignorance. Brahman is fire because the supreme Self consumes ignorance as fire  burns wood. If one knows his own Self he knows Brahman and he knows everything. 
Water refers to  the body because the element of water predominates in it. It also refers to  pure heart in which the ego is subdued. The Supreme Self reflected in the pure  heart destroys ignorance and its effects.
The Mantra says  that the only way to transcend death and realize immortality is to know that  Brahman is one’s own self that is to say knowing that one’s own self and the  supreme Self are identical.
The body is made  of flesh and it will be destroyed one day. But you are the Supreme spirit and  nothing can destroy you. When you have this conviction you conquer death. But  this conviction can come only with through knowledge. There is no other path;  there is no other way to escape the unceasing round of births and deaths.
Mantra 16
sa viśvakṛd viśvavid ātmayonir jñaḥ kālakālo guṇī sarvavidyaḥ / 
    pradhānakṣetrajñapatir guṇeśaḥ saṃsāramokṣasthitibandhahetuḥ // 6.16 // 
He who is the  support of both the unmanifested prakriti and the jiva, who is the Lord of the  three gunas and who is the cause of bondage, existence and Liberation from  samsara, is verily the Creator of the universe, the Knower, the inmost Self of  all things and their Source-the omniscient Lord, the Author of time, the  Possessor of virtues, the Knower of everything. 
The rope is the  support of the illusory snake erroneously super imposed upon it. Further, it is  the reality of the rope that makes the snake appear to be real. It is the same  with the unmanifested prakriti (avyakta) and the jiva,  both of which are erroneously superimposed upon Brahman. Without the substratum  of Brahman neither would appear as real. 
Ignorance about  the Lord brings about the illusion of creation, and the non-discriminating  person becomes entangled in the world. Knowledge of the Lord liberates one from  it.
Mantra 17
sa tanmayo hy amṛta īśasaṃstho jñaḥ sarvago bhuvanasyāsya goptā / 
    sa īśe asya jagato nityam eva nānyo hetur vidyata īśanāya //  6.17 // 
He who  constantly rules the world is verily the cause of bondage and Liberation.  Established in His own glory, He is the Immortal, the Embodiment of  Consciousness, and the omnipresent Protector of the universe. There is no one  else able to rule it. 
Sankara says  that Brahman is samsara-moksha-stithi-bandha-hetuh karanam- that is  Brahman is responsible for our existence, bondage and liberation. 
Many epithets  and adjectives have been used in this Mantra, as elsewhere, to describe  Brahman; yet they are all completely inadequate. Brahman is beyond thought,  beyond speech. Unless some words are used we just cannot even conceive Brahman. 
Mantra 18
yo brahmāṇaṃ vidadhāti pūrvaṃ yo vai vedāṃś ca prahiṇoti tasmai / 
    taṃ ha devam ātmabuddhiprakāśaṃ mumukṣur vai śaraṇam ahaṃ prapadye // 6.18 //  
Seeking  Liberation, I take refuge in the Lord, the revealer of Self-Knowledge, who in  the beginning created Brahma and delivered the Vedas to Him. 
Because the Lord  alone is the cause of a man’s bondage and liberation, the aspirant should take  refuge in Him with heart and soul.  At  the beginning of the cycle, the first tangible manifestation of the attributeless  Brahman in the relative universe is Brahma. Brahma is therefore the personified  totality of the entire created objects.
The teachings of  the Vedas come through a succession of illumined teachers. At the end of the  cycle when the whole universe goes back to the undifferentiated state, there  remains no teacher to preserve and transmit the Vedas. The Vedic knowledge  remains then merged in Brahman. At the beginning of the new cycle, the Lord  creates Brahma and reveals the Vedas to him. Brahma in turn transmits the Vedic  knowledge to a qualified teacher. Thus, a new line of teachers comes into  existence for the preservation and propagation of the Vedic lore.
The seeker of  liberation takes refuge in that luminous Lord who reveals Self-knowledge to the  mind.
Mantra 19 - 20
niṣkalaṃ niṣkriyaṃ śāntaṃ niravadyaṃ nirañjanam / 
    amṛtasya paraṃ setuṃ dagdhendhanam ivānalam // 6.19  // 
yadā carmavad ākāśaṃ veṣṭayiṣyanti mānavāḥ / 
    tadā devam avijñāya duḥkhasyānto  bhaviṣyati // 6.20 // 
When men  shall roll up space as if it were a piece of hide, then there will be an end of  misery without one’s cultivating the Knowledge of the Lord, who is without  parts, without actions, tranquil, blameless, unattached, the supreme bridge to  Immortality, and like a fire that has consumed all its fuel. 
This is a  beautiful way of explaining a difficult topic. The Mantra says that just as it  is never possible to roll up the akasa (sky) as a piece of leather (like  a piece of suit-length cloth) so it is utterly impossible to put an end to  miseries of the world without the knowledge of the Lord. Only when something  impossible happens will misery cease without one’s realizing God in one’s  heart.
That God has been  described in various terms. Brahman is free from the slightest trace of  phenomenality. It is like blazing charcoal which burns radiantly after the wood  is consumed. 
Bhagavad Gita  says
naadatte kasyachit paapam na chaiva sukritam vibhuh
    ajnaanenaavritam jnaanam tena muhyanti jantavah  // 5.15 //
  Nor does the all-pervading Spirit  take on the merit or demerit of any. Knowledge is enveloped in ignorance and  hence beings get deluded.
jnaanena tu tadajnaanam yeshaam naashitamaatmanah
    teshaam aadityavajjnaanam prakaashayati tatparam  // 5.16 //
  But to those whose ignorance is destroyed  by the Knowledge of the Self, that knowledge, like the Sun, reveals the Supreme  (Brahman).
tadbuddhayas tadaatmaanas tannishthaas tatparaayanaah
    gacchantyapunaraavrittim jnaana nirdhoota kalmashaah  // 5.17 //
  Fixing their minds on Him, at one  with Him, abiding in Him, realizing Him alone as the Supreme Goal, they reach a  state, from which there is no return, their sins having been destroyed by their  Knowledge.
Mantra 21
tapaḥprabhāvād devaprasādāt brahma ha  śvetāśvataro 'tha vidvān / 
    atyāśramibhyaḥ paramaṃ pavitraṃ provāca samyag ṛṣisaṅghajuṣṭam // 6.21 // 
Through the  power of austerity and through the grace of the Lord, the sage Svetasvatara  realised Brahman and proclaimed the highly sacred Knowledge, supremely  cherished by the company of seers, to sannyasins of the most advanced  stage. 
The Vedic  teachings have been transmitted through a succession of teachers. When  aspirants devoting themselves to the pursuit of knowledge of Brahman and who  have practiced the proper spiritual disciplines such as control of the senses  and the concentration of mind, follow these teachings, through the grace of  God, they attain liberation.
The Mantra says  that sage Svetasvatara attained Self-Knowledge, by the power of his austerities  and by the grace of the Lord and then he passed on this knowledge to monks who  have renounced the world. 
Mantra 22
vedānte  paramaṃ guhyaṃ purākalpe pracoditam / 
    nāpraśāntāya  dātavyaṃ nāputrāyāśiṣyāya  vā punaḥ // 6.22 // 
The profound  mystery in the Vedanta was taught in the previous cycle. It should not be given  to one whose passions have not been subdued, or to one who is not a son or a  disciple. 
The Upanishads  teach the profound secret that is Knowledge of Brahman which shows the way to  final liberation. This sacred knowledge was to be imparted only to them whose  minds are under control or to the son or a disciple, but even to them it is not  taught if they are not endowed with inner calmness.
The idea is if  this knowledge is imparted to people whose minds are not under control it will  lead to all misinterpretations with disastrous consequences.
Mantra 23
yasya deve parā bhaktir yathā deve tathā gurau / 
    tasyaite kathitā hy arthāḥ prakāśante mahātmanaḥ prakāśante mahātmanaḥ // 6.23 // 
If these  truths have been told to a high-minded person who feels the highest devotion  for God and for his guru as for God, and then they will surely shine forth as  inner experiences - then, indeed, they will shine forth. 
The Upanishad  teachings taught by a Guru bear fruit only for those aspirants who cherish  devotion to the Lord and the teacher. It is God who teaches the disciple  through an illumined human teacher.
As a man whose  clothes are under fire wants nothing but soaking himself in water or a hungry  man wants nothing but a morsel of food, so a noble-minded aspirant, afflicted  with the miseries of phenomenal existence, seeks nothing but the grace of the  Guru, without which the Knowledge of Brahman is indeed hard to attain.
