Crazy wisdom, also known as holy madness, is a manifestation of certain spiritual adepts where they behave in unconventional, outrageous, or unexpected fashion. It is considered to be a universal aspect of spiritual communication, in which the adept employs esoteric and seemingly unspiritual methods to awaken an observer's consciousness. Though associated mainly with Buddhism and Hinduism, it has parallels in others religions, such as the Fools for Christ in Christianity, and the Sufis in Islam.
