In this mudra, the extended forefinger of one hand is enclosed within the fist of the other, a Tantric gesture more common to Buddhism in Japan and Korea. One interpretation is that the erect finger represents Knowledge cloaked in the illusion of the material world. Another version has it that the index finger is man, while the five enclosing fingers of the other hand are the elements of earth, air, fire, water and ether.
The mudra is commonly associated with the radiantly white Vairochana Buddha.
Buddha’s hands are depicted in variety of gestures. Each of these gestures is called a “mudra”. In Sanskrit, the word “mudra” (literally, “seal” or “mark of identity”) is a form of non-verbal communication that refers to symbolic gestures imbued with varied spiritual meanings.
