You should discover your own reality and not thwart yourself. For you have the self as your only friend, or as your only enemy.
The faith of every man, O Arjuna, accords with his nature, Man is made up of faith; as is his faith, so is he. The threefold austerity practiced with faith by men of balanced mind, without any expectation of reward, is said to be pure.
To whom praise and blame are equal, who is silent, content with every fortune, home-renouncing, steadfast in mind, and worships Me, that person is dear to me.
Concerned alone with the upholding of the world, you should act. Whatever the best man does, others do that also. The world follows the standard he sets for himself.
Under the influence of false ego one thinks himself to be the doer of activities, while in reality all activities are carried out by nature as a natural process.
For the soul there is neither birth nor death at any time. He has not come into being, does not come into being, and will not come into being. He is unborn, eternal, ever-existing and primeval. He is not slain when the body is slain.
Whenever there is a decline of righteousness, O Arjuna, and the rise of unrighteousness, then I manifest myself.
They are forever free who renounce all selfish desires and break away from the ego-cage of ‘I’, ‘me’, and ‘mine’ to be united with the Lord. Attain to this, and pass from death to immortality.
As the heat of a fire reduces wood to ashes, the fire of knowledge burns to ashes all karma. 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.
By this attitude of complete renunciation you shall be freed from bondage, good and bad, of karma. You shall be liberated, and come to Me.
