Great Emptiness has no limits. It gives rise neither to feelings of moving or not moving. Nothing detracts from its purity and brightness. This is the mind of wisdom. It is the mind of the Buddhas and bodhisattvas. It is also the ability to help sentient beings.

Neither going out nor coming in,
Without appearance or characteristics,


To practice is to cultivate the mind. If you successfully contemplate the mind, all merits and functions within the mind are at your disposal. But as soon as one thought arises, everything is obscured. If while practicing you feel your mind expanding infinitely, that feeling gives you away. If you suddenly feel, "Ah! I've discovered a limitlessly great expanse! I am liberated!" in reality you are still within the sphere of the limited. Only neither-going-nor-coming is boundless. Being boundless, it has no circumference, so there's no way to find an entrance. To think of leaving is to imagine that there could be a better place, so there is no going either.

When Master T'ai-Hsu had his first enlightenment where he saw limitless light and sound, he felt he was in a very deep far away state. That was still not Great Emptiness since it was not without form. In his second experience there was nothing there that could be explained or described. If there was still something he could describe, it would not be formless.

Countless skillful means Arise out of one mind.
