Bhagavad Geeta Chapter 9 - The Royal Secret
18. I am the goal, the supporter, the Lord, the witness, the abode, the shelter, the friend, the origin, the dissolution, the foundation, the treasure house and the seed imperishable.
Verse 19, 20, 21
19. As sun I give heat; I withold and send forth the rain; I am immortality and also death, both existence and non-existence O Arjuna!
20. The knowers of the three Vedas, the drinkers of soma, purified from sin, 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.
21. They, having enjoyed the vast heaven-world, when their merits are exhausted, enter the world of the mortals; thus abiding by the injunctions
of the three Vedas, desiring (objects of) desires, they attain to the state of 'going and returning' (samsara).
