"Satori is the raison d'etre of Zen, without which Zen is no Zen. Therefore every contrivance, disciplinary and doctrinal, is directed towards satori."[1] Satori can be found in every moment of life, it is wrapped in all daily activities, its goal to unwrap them to see satori.

As an analogy, we may think of a baby when it first walks. After much effort, it stands upright, finds its balance and walks a few steps (kensho), then falls. After continued effort the child will one day find that it is able to walk all the time (satori).

Once the True-Nature has been seen, it is customary to use satori when referring to the enlightenment of the Buddha and the Patriarchs, as their enlightenment was permanent.

The Zen Buddhist experience commonly recognizes enlightenment as a transitory thing in life, almost synonymous with the English term epiphany, and satori is the realization of a state of epiphanic enlightenment. Because all things are transitory according to Zen philosophy, however, the transitory nature of satori is not regarded as limiting in the way that a transitory epiphany would be in Western understandings of enlightenment.
