Shedding of karma with and without ripening in time

Ripening by means (upāyapāka) is forcing karma to rise before its time through excellent, severe austerities and other pure practices, and it gives its fruit at once; ripening by time (kālapāka) is karma ripening by itself in due course and then giving its fruit. Just as fruit ripens on the tree by itself or is ripened by skilled people, aggravated doshas also ripen in two ways, through means (treatment) and through the course of time.
