Acharya Prashant explains that the culmination of all actions in knowledge, as mentioned by Shri Krishna in the Bhagavad Gita, signifies the dissolution of actions. This dissolution means that actions do not leave behind any residues, such as fruits, clutter, or mental dirt. When one acts with wisdom, the action is chosen so wisely that it does not create future obligations, achievements, or heartbreaks. This is the essence of Nishkam Karma, where one does not act for the sake of personal results or gratification. Consequently, the actor is freed from the cycle of euphoria and despair, which are merely residues that bind an individual to the cycle of time and death.
