The Principle of Correspondence As above so below: as below, so above. – The Kybalion This famous saying was created by Hermes. The ancients believed that the macrocosm is a reflection of the microcosm and vice versa. To solve complex paradoxes, we look at what is above us and below us. On a macro level and on a micro level. Because what works for the planets also works for the atoms. And what works for the solar system and atomic system also works for the human system. The Hermetic Philosophy considers that the Universe to be divided into three great classes of phenomena, known as the Three Great Planes, namely: The Great Physical Plane. The Great Mental Plane. The Great Spiritual Plane. These divisions are more or less artificial and arbitrary, all of the three divisions are ascending degrees of the great scale of Life, the lowest point of which is undifferentiated Matter, and the highest point that of Spirit. These planes work in correspondence with one another. Physical, mental, and spiritual are not separated but flow in the same line with different degrees of existence.
