"I bow at the feet of the masters who teach that all phenomena merely arise from conditions, without any self, sentient beings, soul, or creator, and are like a dream, an illusion, a mirage, or an echo.

I bow at the feet of the masters who clearly teach that objects appear to be external, but are merely the habitual propensities of mind, and that even mind, intellect, and consciousness are mere names, mere designations, just emptiness like space.

I bow at the feet of the masters who teach that the aggregates of form and so forth are like foam, water bubbles, a mirage, and so forth, and who teach that the sensory bases are the same as an empty town, the constituents the same as vicious vipers.

I bow at the feet of the masters who teach that all the phenomena of existence and nirvāṇa are birthless and ceaseless, free from going, coming, and remaining, without extremes and middle, each empty of essence."
