Kitab Surangama: Dua Puluh Lima Kaedah Mendapat Makrifat, Sesi Dua, Bahagian 6 daripada 6

"'From distant kalpas until now, my mind has been unobstructed. I remember as many of my past lives as there are sands in the Ganges River.'" "'Having received the Thus Come One's revelation that the enlightened nature is true emptiness - that the nature of emptiness is perfect and blight - I attained Arhatship and suddenly entered into the Thus Come One's sea of magnificent, bright emptiness. With knowledge and views identical with the Buddha, I was certified as being beyond learning. In the liberation of the nature of emptiness, I am unsurpassed. The Buddha asks about perfect penetration. As I have been certified to it, all appearances enter into nothingness; nothingness and what becomes nothingness both disappear. Turning phenomena back to the void is the foremost method.'" Contemplating on the emptiness of all things and then even forsaking the emptiness, that's his method.
