The sensing of external stimuli from the material world enters the body through the senses-organs. The body often responds with involuntary or unconscious bio-chemical processes
Hearing ‘beyond’ the ears.
Needless to say, the traditional Chinese Ch’an Buddhist – Master Xu Yun – had no formal or informal ties or connections to Japanese Zen Buddhism, and never practised (or advocated others to practice) a Japanese Zen that does not follow the Vinaya Disciple, and which deviates from established Ch’an practice.
This is a nonsense statement premised upon the confusion between traditional Chinese Ch’an Buddhism and the very different modern Japanese Zen, and the ignorant conflation of the hua tou technique with the gongan method.
Sitting on a high structure is precarious for an individual, because there is the ever-present danger of ‘falling off’. In such a situation, the practitioner responds by ‘gripping’ ever more tightly to the structure, and will not let go. This is an ‘attachment’ to a lesser state of attainment, an attachment which prevents further progression into the true realms of Ch’an enlightenment.
When sense-organs disengage from sense data, his attainment will be similar to that achieved by a reciter of the Buddha’s name when his training becomes effective and when the Pure Land manifests in front of him. In this state, noumemon and phenomenon intermingle, Mind and Buddha are not a duality and both are in the state of suchness which is absolute and free from all contraries and relativities. Then what difference is there between Chan and Pure Land?
