An ancient worthy once said: “When the blind (a false teacher) leads the blind they are led into a pit of fire.” Today, there are many false teachers and far too many people who are credulous.
Such teachers repeat the sermons of the old masters or reference koans they’ve read in an attempt to appear as wise as the old masters. But they were missing something. They had not personally awakened to the Mind which Siddhartha realized.
All the efforts of these old masters boiled down to this: they were only pointing to the presence of Mind which is unconditioned which gives life to the living; which embraces all beings. Unlike a false teacher they personally realized Mind face-to-face.
These old masters only wanted to awaken their student to this mysterious luminous Mind, but first they had to cut off the thinking of their students which feeds the intellect, providing it with numberless concepts which engender even more thinking and debates. The old masters knew where they were leading their students. They knew what obstructed their intuition of the true Mind.
Making matters even worse, with the institutionalization of Chan/Zen in which the Buddha is said to have wordlessly transmitted the eye of the Dharma to his disciple Mahakasyapa who then wordlessly transmitted it to Ananda and so on down to the present generation, there is really no reason to accept this as little more than Zen fiction, to establish a lineage of false teachers. There is no mention of such a transmission in the old Pali and Agama discourses and is further contradicted by the Mahayana Avatamsaka Sutra which says the great disciples of the Buddha like Mahakasyapa “were not capable of perpetuating the lineage of Buddhas.”
