Zen: Often translated as: The ideal state, ideal harmony, the natural way of things, good.
Actually, Zen is a school of Buddhism. The word is derived from the Sanskrit dhyāna, which means "meditation" and translated via the Chinese Chán to the Japanese Zen.
Zen emphasizes experiential wisdom, particularly as realized in the form of meditation, in the attainment of enlightenment.
As such, it de-emphasizes theoretical knowledge in favor of direct, experiential realization through meditation and dharma (one's righteous duty) practice.
It is difficult to express the feeling behind this word,
