In the advaita analysis, human life and behavior is explained on the basis of the theory of karma, which sets the cycle of rebirths into motion. All actions, good or bad, create their own karmic residues called vAsanas , which exhibit their results over a period of time. The karma which has already started taking fruit is called prArabdha karma. This is the karma that is responsible for the current birth. The accumulated karma which is yet to take fruit is called sancita karma. As long as the cycle of rebirths continues, more karma will be done in the future, and this is called Agamin karma. Liberation (moksha) is the way out of this endless cycle.
