In transmitting the dharma, there is neither explanation nor teaching; there is neighter hearing nor attainment. Since explanations never really explains, nor are they able to teach, why talk about it? Since listening isn't really hearing or attaining anything, then why listen? But say, since it cannot be explained or heard, how can you enter the Way?
But down the bagagge, take of the blinders, and see for yourself that this very place is the valley of the endless spring, this very body is the body of the universe. At such a time, who is it who can accompany this?
