Gita Chapter 9.16 to 9.20

Aham kraturaham yajnah swadhaa’hamahamaushadham;
Mantro’hamahamevaajyam ahamagniraham hutam.
16. I am the Kratu; I am the Yajna; I am the offering (food) to the manes; I am the medicinal herb and all the plants; I am the Mantra; I am also the ghee or melted butter; I am the fire; I am the oblation.

Pitaahamasya jagato maataa dhaataa pitaamahah;
Vedyam pavitramonkaara riksaama yajureva cha.
17. I am the father of this world, the mother, the dispenser of the fruits of actions, and the grandfather; the (one) thing to be known, the purifier, the sacred monosyllable (Om), and also the Rig-, the Sama- and Yajur Vedas.

Gatirbhartaa prabhuh saakshee nivaasah sharanam suhrit;
Prabhavah pralayah sthaanam nidhaanam beejamavyayam.
18. I am the goal, the support, the Lord, the witness, the abode, the shelter, the friend, the origin, the dissolution, the foundation, the treasure-house and the imperishable seed.

Tapaamyahamaham varsham nigrihnaamyutsrijaami cha;
Amritam chaiva mrityushcha sadasacchaahamarjuna.
19. (As the sun) I give heat; I withhold and send forth the rain; I am immortality and also death, existence and non-existence, O Arjuna!

Traividyaa maam somapaah pootapaapaa
Yajnairishtwaa swargatim praarthayante;
Te punyamaasaadya surendraloka-
Mashnanti divyaan divi devabhogaan.
20. The knowers of the three Vedas, the drinkers of Soma, purified of all sins, worshipping Me by sacrifices, pray for the way to heaven; they reach the holy world of the Lord of the gods and enjoy in heaven the divine pleasures of the gods.

Gita Chapter 6.06 to 6.10

Bandhuraatmaa’tmanastasya yenaatmaivaatmanaa jitah;
Anaatmanastu shatrutwe vartetaatmaiva shatruvat.
6. The self is the friend of the self for him who has conquered himself by the Self, but to the unconquered self, this self stands in the position of an enemy like the (external) foe.

Jitaatmanah prashaantasya paramaatmaa samaahitah;
Sheetoshna sukha duhkheshu tathaa maanaapamaanayoh.
7. The Supreme Self of him who is self-controlled and peaceful is balanced in cold and heat, pleasure and pain, as also in honour and dishonour.

Jnaana vijnaana triptaatmaa kootastho vijitendriyah;
Yuktah ityuchyate yogee samaloshtaashmakaanchanah.
8. The Yogi who is satisfied with the knowledge and the wisdom (of the Self), who has conquered the senses, and to whom a clod of earth, a piece of stone and gold are the same, is said to be harmonised (that is, is said to have attained the state of Nirvikalpa Samadhi).

Suhrinmitraary udaaseena madhyastha dweshya bandhushu;
Saadhushwapi cha paapeshu samabuddhirvishishyate.
9. He who is of the same mind to the good-hearted, friends, enemies, the indifferent, the neutral, the hateful, the relatives, the righteous and the unrighteous, excels.

Yogee yunjeeta satatamaatmaanam rahasi sthitah;
Ekaakee yatachittaatmaa niraasheeraparigrahah.
10. Let the Yogi try constantly to keep the mind steady, remaining in solitude, alone, with the mind and the body controlled, and free from hope and greed.
