There is a few mystical works in Persian literature, the authors of which have mentioned into them the foundations of mysticism definitely. These terms can be inferred from mystical and sufical works: “purification, devotion, mystical experience, annihilation, conservation of essence, mystical behaviour, rapture, love, poverty, mystical state, unity of existence, knowledge, Sheykh guidance, religious traditions, Qur’an, holding the beloved mysteries”.The foundations of mysticism, apart from any religious, nationalistic & conditions, can be studied in three point of view: 1. philosophical mys. 2. sufical mys. 3. poetical mys. On the basis of human mystical experiences, we believe that the foundations of mysticism are: The existence of God (the light of lights) ® the manifestation and appearance of the Supreme Being ® the motion of mystic’s soul ® The annihilation or unity of mystic’s soul with the Supreme Being.
