The Bhagavad Gita:

- Since the self is the core of every personality, no one needs to acquire goodness or compassion; they are already there. All that is necessary is to remove the selfish habits that hide them.

- All that we are is the result of what we have thought.

- Better indeed is knowledge than mechanical practice. Better than knowledge is meditation. But better still is surrender of attachment to results, because there follows immediate peace.
