(Lecture given by Master Sheng-yen on the Surangama Sutra on November 4, 1990.) Ch'an is "thus come, thus gone." Everything is Ch'an; this is "thus come." Nothing is Ch'an; this is "thus gone." Today I want to investigate these words. I think they will give you new insights into using Ch'an in your daily life. The Ch'an sect does not believe in establishing set words, descriptions or theories. In fact, Ch'an cannot be expressed in words or phrases. Anything said about Ch'an cannot be true Ch'an. more
