Being Spontaneous in the Taoist sense is different to the meaning we give it in English.
Spontaneity is one of the main concepts in Chuang Tzu. Chuang Tzu and the Taodejing are the two major foundation works of Taoist philosophy. Chuang Tzu is attributed to Chuang Tzu (born circa 369 B.C) and his work simply bears his name.
