The scriptural teachings are all openly revealed explanations, but students do not understand them. Instead, they go to the words and phrases to produce interpretations. All of this is being dependent and falling into cause and effect, so birth and death in the triple world are inevitable.
If you want to get the freedom to go or stay, to take off or put on birth and death, then right now try to recognize the person who is listening to the Dharma.</br>This person has no form, no marks, no basis, no root, nowhere it abides, but it is leaping with life. In all its many kinds of activities, it functions without location. Therefore, if you search for it, the farther away it is, and if you seek it, the more you go against it. It is called the esoteric secret.

Even the multi-part scriptural teachings of the three vehicles are just old paper for wiping away dirt. Buddha is an illusion, an apparition. The ancestral teachers were just old monks.
