In each of these instances, mysticism was the heart of their understanding. It is the same with Christianity and Islam. The Christian tradition rests on Jesus' inner awareness of his relationship with the Father, and Mohammed encountered Allah through the mediation of the Archangel Gabriel. All these religious traditions emerge out of mystical experience, and mystical experience means a direct knowledge of and relationship with the Divine, God, or boundless consciousness. One can almost say that the real religion of humankind isn't religion at all, rather it is mystical spirituality, the bosom out of which the religions themselves have been born.
Mysticism is the awakening to and cultivation of transcendental consciousness.
It is unitive awareness. All forms of mystical wisdom are unitive, that is, non-dual. They contribute to our deeper understanding of the mystery. This is a significant point of convergence among the religions themselves. In mystical consciousness, the transcendent is touched, or is reached, and it touches, embraces us.
