Bhagavad Gita, 4 Wisdom in Action
13: I am their cause, but I myself am changeless and beyond all action.
14: Actions do not cling to me because I am not attached to their results. Those who understand this and practice it live in freedom.
15: Knowing this truth, aspirants desiring liberation in ancient times engaged in action. You too can do the same, pursuing an active life in the manner of those ancient sages.
22: They live in freedom who have gone beyond the dualities of life. Competing with no one, they are alike in success and failure and content with whatever comes to them.
23: They are free, without selfish attachments; their minds are fixed in knowledge. They perform all work in the spirit of service, and their karma is dissolved.
33: The offering of wisdom is better than any material offering, Arjuna; for the goal of all work is spiritual wisdom.
34: Approach those who have realized the purpose of life and question them with reverence and devotion; they will instruct you in this wisdom.
35: Once you attain it, you will never again be deluded. You will see all creatures in the Self, and all in me.
37: As the heat of fire reduces wood to ashes, the fire of knowledge burns to ashes all karma.
38: Nothing in this world purifies like spiritual wisdom. It is the perfection achieved in time through the path of yoga, the path which leads to the Self within.
