Gita Chapter 15.11 to 15.15

Yatanto yoginashchainam pashyantyaatmanyavasthitam;
Yatanto’pyakritaatmaano nainam pashyantyachetasah.
11. The Yogis striving (for perfection) behold Him dwelling in the Self; but, the unrefined and unintelligent, even though striving, see Him not.

Yadaadityagatam tejo jagad bhaasayate’khilam;
Yacchandramasi yacchaagnau tattejo viddhi maamakam.
12. That light which residing in the sun, illumines the whole world, that which is in the moon and in the fire—know that light to be Mine.

Gaam aavishya cha bhootaani dhaarayaamyaham ojasaa;
Pushnaami chaushadheeh sarvaah somo bhootwaa rasaatmakah.
13. Permeating the earth I support all beings by (My) energy; and, having become the watery moon, I nourish all herbs.

Aham vaishwaanaro bhootwaa praaninaam dehamaashritah;
Praanaapaana samaayuktah pachaamyannam chaturvidham.
14. Having become the fire Vaisvanara, I abide in the body of living beings and, associated with the Prana and Apana, digest the fourfold food.

Sarvasya chaaham hridi sannivishto
Mattah smritir jnaanam apohanam cha;
Vedaischa sarvairahameva vedyo
Vedaantakrid vedavid eva chaaham.
15. And, I am seated in the hearts of all; from Me are memory, knowledge, as well as their absence. I am verily that which has to be known by all the Vedas; I am indeed the author of the Vedanta, and the knower of the Vedas am I.

Gita Chapter 11.01 to 11.05

Arjuna Uvaacha:
Madanugrahaaya paramam guhyamadhyaatmasamjnitam;
Yattwayoktam vachastena moho’yam vigato mama.
Arjuna said:
1. By this explanation of the highest secret concerning the Self, which Thou hast spoken out of compassion towards me my delusion is gone.
COMMENTARY: After hearing the glories of the Lord, Arjuna has an intense longing to have the wonderful Cosmic Vision.

Bhavaapyayau hi bhootaanaam shrutau vistarasho mayaa;
Twattah kamalapatraaksha maahaatmyamapi chaavyayam.
2. The origin and the destruction of beings verily have been heard by me in detail from Thee, O lotus-eyed Lord, and also Thy inexhaustible greatness!

Evametadyathaattha twamaatmaanam parameshwara;
Drashtumicchaami te roopamaishwaram purushottama.
3. (Now), O Supreme Lord, as Thou hast thus described Thyself, O Supreme Person, I wish to see Thy Divine Form!

Manyase yadi tacchakyam mayaa drashtumiti prabho;
Yogeshwara tato me twam darshayaatmaanamavyayam.
4. If Thou, O Lord, thinkest it possible for me to see it, do Thou, then, O Lord of the Yogis, show me Thy imperishable Self!

Sri Bhagavaan Uvaacha:
Pashya me paartha roopaani shatasho’tha sahasrashah;
Naanaavidhaani divyaani naanaavarnaakriteeni cha.
The Blessed Lord said:
5. Behold, O Arjuna, My forms by the hundreds and thousands, of different sorts, divine and of various colours and shapes!

Gita Chapter 5.01 to 5.05

Arjuna Uvaacha:
Sannyaasam karmanaam krishna punar yogam cha shamsasi;
Yacchreya etayorekam tanme broohi sunishchitam.
Arjuna said:
1. Renunciation of actions, O Krishna, Thou praisest, and again Yoga! Tell me conclusively which is the better of the two.

Sri Bhagavaan Uvaacha:
Sannyaasah karmayogashcha nihshreyasakaraa vubhau;
Tayostu karmasannyaasaat karmayogo vishishyate.
The Blessed Lord said:
2. Renunciation and the Yoga of action both lead to the highest bliss; but of the two, the Yoga of action is superior to the renunciation of action.

Jneyah sa nityasannyaasi yo na dweshti na kaangkshati;
Nirdwandwo hi mahaabaaho sukham bandhaat pramuchyate.
3. He should be known as a perpetual Sannyasin who neither hates nor desires; for, free from the pairs of opposites, O mighty-armed Arjuna, he is easily set free from bondage!
COMMENTARY: A man does not become a Sannyasin by merely giving up actions due to laziness, ignorance, some family quarrel or calamity or unemployment. A true Sannyasin is one who has neither attachment nor aversion to anything. Physical renunciation of objects is no renunciation at all. What is wanted is the renunciation of egoism and desires.

Saankhyayogau prithagbaalaah pravadanti na panditaah;
Ekam apyaasthitah samyag ubhayor vindate phalam.
4. Children, not the wise, speak of knowledge and the Yoga of action or the performance of action as though they are distinct and different; he who is truly established in one obtains the fruits of both.

Yatsaankhyaih praapyate sthaanam tad yogair api gamyate;
Ekam saankhyam cha yogam cha yah pashyati sa pashyati.
5. That place which is reached by the Sankhyas or the Jnanis is reached by the (Karma) Yogis. He sees who sees knowledge and the performance of action (Karma Yoga) as one.

Gita Chapter 4.26 to 4.30

Shrotraadeeneendriyaanyanye samyamaagnishu juhwati;
Shabdaadeen vishayaananya indriyaagnishu juhwati.
26. Some again offer hearing and other senses as sacrifice in the fire of restraint; others offer sound and various objects of the senses as sacrifice in the fire of the senses.

Sarvaaneendriya karmaani praanakarmaani chaapare;
Aatmasamyamayogaagnau juhwati jnaanadeepite.
27. Others again sacrifice all the functions of the senses and those of the breath (vital energy or Prana) in the fire of the Yoga of self-restraint kindled by knowledge.

Dravyayajnaas tapoyajnaa yogayajnaastathaapare;
Swaadhyaayajnaana yajnaashcha yatayah samshitavrataah.
28. Some again offer wealth, austerity and Yoga as sacrifice, while the ascetics of self-restraint and rigid vows offer study of scriptures and knowledge as sacrifice.

Apaane juhwati praanam praane’paanam tathaa’pare;
Praanaapaana gatee ruddhwaa praanaayaamaparaayanaah.
29. Others offer as sacrifice the outgoing breath in the incoming, and the incoming in the outgoing, restraining the courses of the outgoing and the incoming breaths, solely absorbed in the restraint of the breath.
COMMENTARY: Some Yogis practise inhalation, some practise exhalation, and some retention of breath. This is Pranayama.

Apare niyataahaaraah praanaan praaneshu juhwati;
Sarve’pyete yajnavido yajnakshapita kalmashaah.
30. Others who regulate their diet offer life-breaths in life-breaths; all these are knowers of sacrifice, whose sins are all destroyed by sacrifice.

Gita Chapter 4.21to 4.25

Niraasheer yatachittaatmaa tyaktasarvaparigrahah;
Shaareeram kevalam karma kurvannaapnoti kilbisham.
21. Without hope and with the mind and the self controlled, having abandoned all greed, doing mere bodily action, he incurs no sin.

Yadricchaalaabhasantushto dwandwaateeto vimatsarah;
Samah siddhaavasiddhau cha kritwaapi na nibadhyate.
22. Content with what comes to him without effort, free from the pairs of opposites and envy, even-minded in success and failure, though acting, he is not bound.

Gatasangasya muktasya jnaanaavasthitachetasah;
Yajnaayaacharatah karma samagram pravileeyate.
23. To one who is devoid of attachment, who is liberated, whose mind is established in knowledge, who works for the sake of sacrifice (for the sake of God), the whole action is dissolved.

Brahmaarpanam brahmahavirbrahmaagnau brahmanaa hutam;
Brahmaiva tena gantavyam brahmakarmasamaadhinaa.
24. Brahman is the oblation; Brahman is the melted butter (ghee); by Brahman is the oblation poured into the fire of Brahman; Brahman verily shall be reached by him who always sees Brahman in action.
COMMENTARY: This is wisdom-sacrifice, wherein the idea of Brahman is substituted for the ideas of the instrument and other accessories of action, the idea of action itself and its results. By having such an idea the whole action melts away.

Daivam evaapare yajnam yoginah paryupaasate;
Brahmaagnaavapare yajnam yajnenaivopajuhwati.
25. Some Yogis perform sacrifice to the gods alone, while others (who have realised the Self) offer the Self as sacrifice by the Self in the fire of Brahman alone.
