Satori (悟り) is a Japanese Buddhist term for awakening, "comprehension; understanding". It is derived from the Japanese verb satoru.
In the Zen Buddhist tradition, satori refers to the experience of kenshō, "seeing into one's true nature". Kenmeans "seeing," shō means "nature" or "essence".
Satori and kenshō are commonly translated as enlightenment, a word that is also used to translate bodhi, prajna and buddhahood.
Satori is often used interchangeably with kenshō. Kenshō refers to the perception of the Buddha-Nature or emptiness. According to some authors, kenshō is a brief glimpse, while satori is considered to be a deeper spiritual experience.
Distinct from this first insight, daigo-tettei is used to refer to a "deep" or lasting realization of the nature of existence.
