The mystery of Fire itself, or the dynamic central systemic force. The secret of the first aspect. The secrets, as imparted sequentially to the initiate, are roughly three in number, though within them may be found lesser mysteries which are earlier revealed. At the third initiation the first of the three fundamental secrets of the solar system is imparted to the initiate, immediately after he has taken the oath. It concerns the phenomena of the dense objective manifestation of the Logos.
Students are apt to forget that our seven planes are the seven subplanes of the cosmic physical.
This has a very definite bearing on the secret of electricity. This is why the secret is not revealed till the third initiation, and is prepared for by the impartation of two lesser secrets which concern the physical and astral planes, and which are imparted at the first two initiations by the Bodhisattva. Electrical phenomena are scientifically recognized as dual in nature, but the inherent triplicity of electricity is as yet but a matter for speculation for modern science. The fact that it is triple is demonstrated to the initiate at the first initiation, and the secret of how to balance forces on the physical plane, and thereby produce equilibrium, is revealed to him at the first initiation. This he seldom does, as the results gained thereby are practically unimportant and he wastes not energy in this manner.
