To be born again is to enter into the new life, that of the Kingdom of God, of the Universal White Brotherhood. Taking the image of the source as a starting point, the Master, Omraam Mikhaël Aïvanhov, interprets the words of Jesus: "...unless one is born of water and the Spirit, he cannot enter the Kingdom of God." The water Jesus speaks of is love. The spirit, the fire, is wisdom. Love and wisdom unite to give birth to the truth, which is the new life. The interpretation of these words, which is the key to spiritual work, will continue throughout this book and beyond. Starting from three virtues: love, wisdom, truth, Master Omraam Mikhaël Aïvanhov very simply reveals the psychic structure of man: heart, mind, will. He then explains that our physical body is a reflection of our psychic entity, showing us how Cosmic Intelligence imprinted love in our mouth, wisdom in our ears, truth in our eyes... This book, which is the first in a large series, lays the essential foundations of the Teachings of Master Omraam Mikhaël Aïvanhov. It is also particularly revealing of his way of thinking, where the Holy Scriptures, inner symbols, and the sciences of man and nature meet and complement each other in an immense synthesis.
