(Lecture given on the Surangama Sutra by Master Sheng-yen on December 14, 1986.) In the passage from the sutra that we will discuss today, the Buddha discusses the twelve ayatanas, or entries, and he speaks about the sense organ of the eye and its object. When the six sense organs (eye, ear, nose, tongue, body, mind) come into contact with the six sense objects (what is seen, heard, smelled, tasted, felt, thought), they comprise the twelve ayatanas.more
