Revelation, the self-communication of God; that is, God's disclosure of divine being or divine will to human beings. Most of the major world religions affirm revelation in some sense as a basis for their doctrines and practices. Revelation may be in the form of a vision, often accompanied by words, or may consist only of words. In the Old Testament, Moses saw a burning bush and heard God's voice proceeding from it (see Exodus 3). Muhammad heard a noise like a bell that resolved itself into words. As recounted in the Hindu epic the Bhagavad-Gita Prince Arjuna saw his charioteer Krishna transformed into his true form as a divine being. Historical events may also be understood as revelation—for instance, the exodus of Israel from Egypt, or the life of Jesus Christ. General revelation refers to the knowledge of God communicated through the order of nature, a conception that is found in Eastern religion and in some Romantic poetry, such as that of the English poet William Wordsworth. Special revelation refers to the knowledge of God that comes through specific experiences, such as visions, dreams, or events. The two kinds of revelation may be complementary. Christianity and Islam both teach that the natural order is revelatory of God, but their emphasis is on the special revelations communicated by their founders. In Judaism too the special revelations given to Moses and the prophets, which are described in the Bible, are fundamental to the faith. In all revelation, the primary element is the encounter with the divine, which it is the task of religious doctrine and of religious tradition to interpret and convey.
