3.142

經曰：「菩提之道不可圖度，高而無上、廣不可極，淵而無下、深不可測，大包天地、細入無間，故謂之道。」

A scripture states: 'The Way of bodhi cannot be conceived or measured: high without an above, vast without an extreme, deep without a bottom, profound without being fathomed; in greatness it envelops heaven and earth, in subtlety it enters where there is no space between; therefore it is called the Way.'
