Let's discuss various findings and common occult beliefs and try to put them into a context that is largely scientific, rather than mystic, in approach. Often, people mention things in the occult without explaining a good theory (specifically a working model and not a singular hypothesis or observation) of how the physical and astral planes (perhaps more?) work together to create various effects. For example, the Kabbalah can be thought of as a good diagram for how various elements interact (whether through the Hermetic tradition, planetary magick, or Jew magick)–however, I can't help but be reminded of the thermodynamic square diagram (pic related). One cannot say that they understand thermodynamics at all if they've only memorized the diagram. It is only useful as a mnemonic tool, and should not be used as an introduction with later justifications–such would be a mystical approach and not a rigorous one.
Lectures and authors who've sought to use empirical research (like Robert Bruce) should be preferred, as well as your own speculations. We can also try to formulate the scientific underpinnings of various aspects of high magick, like astral correspondences being used to summon a planetary sphere to your location.
Things that we should focus the most on
Definitions and semantics, to avoid confusion and foster scientific-thinking.
Many terms like "egregore, demon, angel, tulpa," require careful definition. Is an egregore distinct from a tulpa? If so, on what basis? What is the difference between a soul and spirit?
