The Dharma of Mind Transmission

The Mind is neither large nor small; it is located neither within nor without. It should not be thought about by the mind nor be discussed by the mouth. Ordinarily, it is said that we use the Mind to transmit the Mind, or that we use the Mind to seal the Mind. Actually, however, in transmitting the Mind, there is really no Mind to receive or obtain; and in sealing the Mind, there is really no Mind to seal. If this is the case, then does the Mind exist or does it not exist? Actually, it cannot be said with certainty that the Mind either exists or does not exist, for it is Absolute Reality. This is expressed in the Ch'an Sect by the maxim: "If you open your mouth, you are wrong. If you give rise to a single thought, you are in error." So, if you can quiet your thinking totally, all that remains is voidness and stillness.
