Occult simply means ""non-observable", "scalar", "hidden", "mysterious", "unknown" or yet to be known. It does not mean "satanic", "evil" or anything resembling or derived from such emotionally reactionary terms (meme) taught by the controlling power structures. There is no supernatural but there are the unseen causative etheric scalar forces.
Science and scientists are constantly pursuing new, hidden or occult knowledge - that which they do not yet know. Spiritual seekers, regardless of venue, are seeking to know new knowledge or new awareness whether from the Bible or other sacred text. They are digging into the hidden meanings looking for that which is unknown or occulted from their current knowledge or understanding.
"Comparing it (etheric vapor) with steam it is as different as it is opposite in origin. Steam is derived from heat or combustion, and so may be said to have a chemical origin; the vapor is a production of mechanical action, a spontaneous energy. Vibration, whether considered as an energy or a motion, is an inherent property or concomitant of matter, and therefore spontaneous. Keely’s inventions for producing this power are so entirely original, and so unlike any other devices that have been constructed, that there is nothing in the annals of research to afford a starting point for the understanding. The mechanical means by which this occult energy under consideration is educed and economized, are as unique as those which belong to electricity. Keely’s instruments are no more like electrical apparatus than they are like the machinery used with steam, the product of the crude molecular dissociation of water by heat." [Bloomfield-Moore in Keely and His Discoveries]
Walter Russell on occult
Question: What do you think was meant by saying it was dangerous to meditate without a guide?
Answer: "It must have referred to cultist who go in for phenomena, such as spirit rappings and table liftings. People do get so deeply immersed in the unnatural and miraculous happenings that they do become mentally deranged â€” but ignorance of Nature's ways lied behind such practices. Also, the eternal ego of man lies behind it. Many people like to think that they are 'occult' whatever that means. People who are given to day-dream about doing miraculous things but never do anything at all, or who suffer from what is known as 'delusions of grandeur' are the ones who like to feel that they are 'occult' and can perform miracles because of it. That is the danger of taking up such unnatural things with such unnatural people." (Russell, The Message of the Divine Iliad; VOL II, page 209)
