Other than sacrality, the thing that one does not need to explain for it to be valid and life-determining, the numinous can surely be explained in part as a matter of some kind of electricity and magnetism. The brain as an organ that translates electrical energies into chemical responses, ‘feelings’ and actions. These energies do not only arrive from within the body. The universe is a cauldron of radiation, organized in clockworks within clockworks within clockworks.
Almost all mystical schools use astrology as their main science. Astrology charts the motions of the clockwork of which we are most directly part. Some schools work with more detail than others. The moon is always involved. The elements of an astrological chart point to the arms in the clockwork of energies. We are born into a certain energetic constitution - as we leave the womb we are tuned to a certain state of affairs, and this remains with us and directs our course (allows it to be directed by the further progression of the clockworks) of with a peculiar consistency.
Whenever I experience the numinous strongly, I notice that normal, linear causality begins to lose its explanatory power. Inexplicable and inspiring or frightening event begin to pile up. I will dream of a person I have never met and the next day meet that person, or I will read a story about a suicide and the next day get a call that a friends friend has killed himself. I think that a numinous feeling represents an extraordinary concentration of subtle causal forces. The causalities that less direct in their effect then gravity, mass - forces that work directly on the psyche, and on mans collective ‘consciousness’, the currents that direct his mass-movements. In this way ‘synchronicity’ can be explained.
As the clockworks of subtler causal forces work their influence, they direct man ‘insidiously’, they guide him, influence thoughts, determine his interpretation of his instinctive intentions. The subtle gives form the the raw. The ‘heavenly forces’ as the pagan traditions would call the astrological energies form a web of ‘suggestion’ that, since it is invisible, works more like a command than a suggestion. As we defiantly may resist direct orders and refuse to face up to obvious necessities, we are carried along meekly by the subtle influence we can not perceive, and thus can not resist.
Whenever we feel the presence of God, the subtle influences have made themselves known to us.
