[217] How is wisdom in the state of mastery — through being endowed with two powers, through the tranquilization of three formations (saṅkhāra), through sixteen modes of the conduct of knowledge (ñāṇa), and through nine modes of the conduct of concentration (samādhi) — knowledge of the attainment of cessation (nirodhasamāpatti)?
"Through two powers": there are two powers — the power of serenity (samathabala) and the power of insight (vipassanābala).
