(Greek) Literally, "prince" or "ruler." Esoterically, primordial planetary spirits.
"We have previously stated that the Golden Fleece, the Treasury of the Light, is found within the profundities of oneself. Unquestionably, the Archons of the Fate and the Rulers of the Aeons and those of the Sphere turn to the matter of their refuse. They subdue it, devour it, subjugate it, govern it, and do not let it go to become Souls in the world. This means that they, the Rulers, maintain the elemental Essences in their respective Kingdoms. Such elemental Essences are governed by the Archons. However, while the elemental Essences develop, they pass from one Kingdom to another, according to the Law. Every elemental Essence can convert itself into a human Soul, at its time and hour, and according to the Law. [...] The Archons of the Twelve Aeons, their Lords and their Authorities, their Angels and their Archangels, are represented within ourselves by the distinct autonomous and self-conscious parts of our own Being. The powers of the Rulers of the Aeons, and those of the Fate and those of the Sphere are found within our own Soul." - Samael Aun Weor, The Gnostic Bible: The Pistis Sophia Unveiled
"...the Archons are the diverse, autonomous and Self-conscious parts of our own Being. [...] The violent judgements of the evil Archons fall upon those who violate the Law. The terms good and evil are very discussable. Something is good when it is suitable for us and evil when it is not suitable for us. Evil Rulers must be understood in esoteric form. No one can enjoy the violent judgements of the Lords of Karma. This is why they are symbolically denominated as evil Archons. We need to be saved from the Archons or violent Rulers of darkness and also from the violent receivers of the outermost darkness." - Samael Aun Weor, The Gnostic Bible: The Pistis Sophia Unveiled
