Gita Chapter 8.26 to 8.28

Shuklakrishne gatee hyete jagatah shaashwate mate;
Ekayaa yaatyanaavrittim anyayaa’vartate punah.
26. The bright and the dark paths of the world are verily thought to be eternal; by the one (the bright path) a person goes not to return again, and by the other (the dark path) he returns.
COMMENTARY: The bright path is the path to the gods taken by devotees. The dark path is of the manes taken by those who perform sacrifices or charitable acts with the expectation of rewards.

Naite sritee paartha jaanan yogee muhyati kashchana;
Tasmaat sarveshu kaaleshu yogayukto bhavaarjuna.
27. Knowing these paths, O Arjuna, no Yogi is deluded! Therefore, at all times be steadfast in Yoga.

Vedeshu yajneshu tapahsu chaiva
Daaneshu yat punyaphalam pradishtam:
Atyeti tatsarvam idam viditwaa
Yogee param sthaanamupaiti chaadyam.
28. Whatever fruits or merits is declared (in the scriptures) to accrue from (the study of) the Vedas, (the performance of) sacrifices, (the practice of) austerities, and (the offering of) gifts—beyond all these goes the Yogi, having known this; and he attains to the supreme primeval (first or ancient) Abode.

Hari Om Tat Sat

Iti Srimad Bhagavadgeetaasoopanishatsu Brahmavidyaayaam

Yogashaastre Sri Krishnaarjunasamvaade

Aksharabrahmayogo Naama Ashtamo’dhyaayah

Thus in the Upanishads of the glorious Bhagavad Gita, the science of the Eternal, the

scripture of Yoga, the dialogue between Sri Krishna and Arjuna, ends the eighth discourse entitled:

“The Yoga Of the Imperishable Brahman”

Yajnashishtaamritabhujo yaanti brahma sanaatanam;
Naayam loko’styayajnasya kuto’nyah kurusattama.
31. Those who eat the remnants of the sacrifice, which are like nectar, go to the eternal Brahman. This world is not for the man who does not perform sacrifice; how then can he have the other, O Arjuna?
COMMENTARY: They go to the eternal Brahman after attaining knowledge of the Self through purification of the mind by performing the above sacrifices. He who does not perform any of these is not fit even for this miserable world. How then can he hope to get a better world than this?

Evam bahuvidhaa yajnaa vitataa brahmano mukhe;
Karmajaan viddhi taan sarvaan evam jnaatwaa vimokshyase.
32. Thus, various kinds of sacrifices are spread out before Brahman (literally at the mouth or face of Brahman). Know them all as born of action, and knowing thus, thou shalt be liberated.

Shreyaan dravyamayaadyajnaaj jnaanayajnah parantapa;
Sarvam karmaakhilam paartha jnaane parisamaapyate.
33. Superior is wisdom-sacrifice to sacrifice with objects, O Parantapa! All actions in their entirety, O Arjuna, culminate in knowledge!

Tadviddhi pranipaatena pariprashnena sevayaa;
Upadekshyanti te jnaanam jnaaninas tattwadarshinah.
34. Know that by long prostration, by question and by service, the wise who have realised the Truth will instruct thee in (that) knowledge.

Yajjnaatwaa na punarmoham evam yaasyasi paandava;
Yena bhootaanyasheshena drakshyasyaatmanyatho mayi.
35. Knowing that, thou shalt not, O Arjuna, again become deluded like this; and by that thou shalt see all beings in thy Self and also in Me!

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 3.11 to 3.15

Devaan bhaavayataanena te devaa bhaavayantu vah;
Parasparam bhaavayantah shreyah param avaapsyatha.
11. With this do ye nourish the gods, and may the gods nourish you; thus nourishing one another, ye shall attain to the highest good.

Ishtaan bhogaan hi vo devaa daasyante yajnabhaavitaah;
Tair dattaan apradaayaibhyo yo bhungkte stena eva sah.
12. The gods, nourished by the sacrifice, will give you the desired objects. So, he who enjoys the objects given by the gods without offering (in return) to them, is verily a thief.

Yajnashishtaashinah santo muchyante sarva kilbishaih;
Bhunjate te twagham paapaa ye pachantyaatma kaaranaat.
13. The righteous, who eat of the remnants of the sacrifice, are freed from all sins; but those sinful ones who cook food (only) for their own sake, verily eat sin.

Annaad bhavanti bhootaani parjanyaad anna sambhavah;
Yajnaad bhavati parjanyo yajnah karma samudbhavah.
14. From food come forth beings, and from rain food is produced; from sacrifice arises rain, and sacrifice is born of action.

Karma brahmodbhavam viddhi brahmaakshara samudbhavam;
Tasmaat sarvagatam brahma nityam yajne pratishthitam.
15. Know thou that action comes from Brahma, and Brahma proceeds from the Imperishable. Therefore, the all-pervading (Brahma) ever rests in sacrifice.
