Hip Glossary: Kensho
Kensho:Kenshō literally "seeing the nature" in Japanese, is the experience of enlightenment described in the context of Zen Buddhism. The term is often used to denote an initial awakening experience, seeing one’s True-Nature or Buddha-Nature, that can be enlarged and clarified through further practice in daily life.
In Kensho, one experiences the illusionary nature of the separate self ("I"). Because of the nature of the mind, any perception seems to involve a perceived object, the process of perception, and a perceiving subject. For example, ‘I see you’: I – the subject (which appears to be separate from the perceived objects), see – the process of perception, you – the object. Trying to find the "I," the subject, through introspection leads to the realisation that this "I" is completely dependent on the process of perception, the associated thought/feeling complex, and the memories tied to them.
