Passage: Religious knowledge or "vision" was indicated as a result of practice both within and outside of the Buddhist fold. According to the Samannaphala Sutta, this sort of vision arose for the Buddhist adept as a result of the perfection of "meditation" coupled with the perfection of "discipline" (Pali sila; Skt. sila). Some of the Buddha's meditative techniques were shared with other traditions of his day, but the idea that ethics are causally related to the attainment of "transcendent wisdom" (Pali panna; Skt. prajna) was original.[web 18] Question: There is an idea where ethics are causally related to the attainment of what?
transcendent wisdom
