The embodied human consciousness has four spiritual centers that are necessary for life. They are inborn as potentials for all human beings, but they do not develop or activate without the correct attitude and practices.
The first is the belly center, which has to do with the physical body and the embodiment of our presence. It is also the center responsible for action and movement. The second, the heart, in the center of the chest, is the seat of our feelings and the conduit of the love energy, sensitivity, and personal contact. Our mind is the third center, which is the discerning intelligence. The fourth center is located over the head and outside of the physical body. When the first three centers have opened and developed, and they function together in a balanced way, the fourth is ignited, which means that the conduit of the individual consciousness is awake to itself as Living Being manifesting in human form. It is said that when the fourth center opens, our real life has begun to be lived. – The Power of Divine Eros: The Illuminating Force of Love in Everyday Life, Ch. 10
