The explanation says: 'Gate' means the root, the place through which radiant principle exits and enters; exit and entry arise from the root. The Śākya teaching has the Non-dual Dharma Gate; Laozi speaks of the Gate of All Wonders; the Book of Documents says 'Misfortune and fortune have no gate.' All these are the groves of comprehensive penetration and the deep abysses of subtle function. A person who leaves home attains this meaning. Sang means extinction: extinguishing the toil of defilements and penetrating spiritual liberation—that is sangmen. Or sang may simply be a scribal error for cheng (vehicle): the 'Vehicle Gate' is the Great Vehicle Gate. When troublesome thoughts are extinguished, whatever one encounters is ridden upon; therefore, first it was called the Gate of Extinction, and later the Vehicle Gate. Moreover, the eighty-four thousand [teachings] are all called Dharma gates; why should there be only the two gates of sang and sang?
