Theravada Bhikkhu Bodhi explains: :Kukkucca is worry or remorse after having done wrong. Its characteristic is subsequent regret. Its function is to sorrow over what has and what has not been done. It is manifested as remorse. Its proximate cause is what has and what has not been done (i.e. wrongs of commission and omission). Nina van Gorkom explains: :The characteristic of kukkucca is repentance. Repentance is generally considered a virtue, but the reality of kukkucca is not wholesome, it arises with dosa-mūla-citta (see
Dvesha_(Buddhism)). Kukkucca which “regrets” the commission of evil and the omission of kusala is different from wholesome thinking about the disadvantages of akusala and the value of kusala. The conventional term “worry” which is also used as translation of kukkucca may not be clear either. When we say that we worry, it may not be the reality of kukkucca but it may be thinking with aversion about an unpleasant object without there being kukkucca. For example, we may worry about the way how to solve a problem in the future; this kind of worry is not the reality of kukkucca. ==See also==
