In Shingon, Mahavairocana Tathagata ("Dainichi Nyorai" 大日如來) is the universal or Adi-Buddha that is the basis of all phenomena, present in each and all of them, and not existing independently or externally to them. The goal of Shingon is the realization that one's nature is identical with Mahavairocana, a goal that is achieved through initiation, meditation and esoteric ritual practices. This realization depends on receiving the secret doctrines of Shingon, transmitted orally to initiates by the school's masters. The "Three Mysteries" of body, speech, and mind participate simultaneously in the subsequent process of revealing one's nature: the body through devotional gestures (mudra) and the use of ritual instruments, speech through sacred formulas (mantra), and mind through meditation.
