[221] "The power of insight (vipassanābala)": in what sense is it the power of insight (vipassanā)? Through the contemplation of impermanence (aniccānupassanā) one is not shaken by the perception of permanence (niccasaññā) — thus it is the power of insight. Through the contemplation of suffering (dukkhānupassanā) one is not shaken by the perception of pleasure (sukhasaññā) — thus it is the power of insight. Through the contemplation of non-self (anattānupassanā) one is not shaken by the perception of self (attasaññā) — thus it is the power of insight. Through the contemplation of disenchantment (nibbidānupassanā) one is not shaken by delight (nandi) — thus it is the power of insight. Through the contemplation of dispassion (virāgānupassanā) one is not shaken by lust (rāga) — thus it is the power of insight. Through the contemplation of cessation (nirodhānupassanā) one is not shaken by the origin — thus it is the power of insight. Through the contemplation of relinquishment (paṭinissaggānupassanā) one is not shaken by grasping (ādāna) — thus it is the power of insight. One is not shaken, does not waver, does not tremble because of ignorance, because of the defilements (kilesa) accompanied by ignorance, and because of the aggregates — thus it is the power of insight. This is the power of insight.
