It is also called half-night heart-suture. Translated by the Tang Dynasty dynasty (玄奘). Bodhisattva Bodhisattva Gwanjae describes the appearance of the Dharma through the banya meditation step by step. The 12 smokes are also empty, and the four truths are also empty, indicating the empty principles of all laws. In particular, the principle of emptiness, represented by 'color, immediate, public, and immediate colors', indicates that there is no fixed nature for any object, and only the Bodhisattva can attain the highest wisdom through the practice of prana paramil. It can be obtained, and such a reason is also mysterious and ends as a mantra.
