Kenshō (見性) is a Japanese term from the Zen tradition. Ken means "seeing", shō means "nature, essence". It is usually translated as "seeing one's (true) nature", that is, the Buddha-nature or nature of mind.
Kenshō is an initial insight or awakening, not full Buddhahood. It is to be followed by further training to deepen this insight, and learn to express it in daily life.
The term kenshō is often used interchangeably with satori, which is derived from the verb satoru, and means "comprehension; understanding"
