BG 3.28-30
But he, O mighty-armed, who knoweth the essence of the divisions of the qualities and functions, holding that "the qualities move amid the qualities," is not attached.

Surrendering all actions to Me, with thy thoughts resting on the supreme Self, from hope and egoism freed, and of mental fever cured, engage in battle.
