Karma done with the Buddhi's deliberation, letting go of attachment to the fruit, is called “niṣkāma karma”. That is “Buddhi Yoga”. Unless the Buddhi is pure, attachment to the fruit cannot be given up, can it? So that is also called “Yoga Buddhi”. With its help alone, free yourself from the bonds of karma, and become one who has gone beyond karma. Suppose someone thinks, 'Let me simply not do the karmas that bring bondage.' That is not possible. It is not possible to remain without doing karma at all. No one can do that. That is why, in the third chapter of the Gītā, Kṛṣṇa says, “Not anyone, even for a moment.”
