As birds and deer do not approach a burning mountain, so evil never approaches those who know the Supreme Truth (Brahman).
What is without thought, though in the center of thought, what cannot be thought, the hidden, the highest – let a man merge his thought there; then will this living being be free from attachment.
Meditation should be directed to the highest being within; then the unclear understanding becomes clear.
By self discipline goodness is obtained; from goodness understanding is reached; from understanding the Self is known; and he who has known his True Self does not return to this world.
