The great Japanese Master Hakuin wrote, “If you take up one koan and investigate it unceasingly, your mind will die and your will will be destroyed. It is as though a vast, empty abyss lay before you, with no place to set your hands and feet. You face death and your bosom feels as though it were on fire. Then suddenly you are one with the koan, and body and mind are cast off…. This is known as seeing into one’s nature.”
This sounds like the crossroads between complete mastery and brainwashing.
