When one displays the buddha mudra with one's whole body and mind, sitting upright in this samadhi even for a short time, everything in the entire dharma world becomes buddha mudra, and all space in the universe completely becomes enlightenment. Therefore, it enables buddha-tathagatas to increase the dharma joy of their own original grounds and renew the adornment of the way of awakening. Simultaneously, all living beings of the dharma world in the ten directions and six realms become clear and pure in body and mind, realize great emancipation, and their own original face appears. At that time, all things together awaken to supreme enlightenment and utilize the buddha-body, immediately go beyond the culmination of awakening, and sit upright under the kingly bodhi tree. At the same time, they turn the incomparable, great dharma wheel and begin expressing ultimate and unfabricated profound prajna.

Furthermore, throughout the Dharma worlds in ten directions, ordinary beings of the three states (the three miserable worlds of hell, hungry ghosts and animals) and the six states (the three miserable worlds plus the worlds of asuras, humans and gods) all become clear and pure in body and mind at once; they experience the state of great and their original features appear.
