By knowledge do you mean "understanding" - such as that what can only be gained from experience, or is it something else?
Yes, correct.
Going beyond the physical plane. Reaching the spiritual plane, the dimensions beyond the physical. Going beyond the lower mind to "see" and "perceive" beyond.
The physical plane is a limit/boundary, which must be crossed, in the correct way. The lower mind is also a limit/boundary, because it does not allow you to go "beyond," remaining anchored on this plane of existence, without evolving.
Pluto literally rules everything connected with the underground. Mines, caves, tunnels etc..
Ades, which represents, the lowest point, the abyss, is also related to the first chakra in the soul. Hell is associated with the realm of ades, in the various corruptions, connected with the color red, "the infernal flames."
The first chakra is the "lowest" point of the soul, "below him there is nothing else."
Just as Zeus, who rules the heavenly realms, connected with Jupiter, the 7 chakra is corrupted by the enemy with the "Jewish heaven."
"Upward expansion."
In the glyph of Sagittarius, it can be seen how the arrow is pointing "upward." The "thrust of expansion," toward the divine, the spiritual plane. Olympus.
Its upper octave is spirituality, the Divine; its lower octave is excess.
This can also manifest on the astrological level. Jupiter in some cases, although considered "positive," can manifest its lower octave, in people's lives. Just as in world events, it can cause "negative" situations in excess.
Zeus, in certain areas had no limits, and create strong problems due to excesses(lower octave). No rules, no stakes, no restrictions, no regulations. To impose these things on Zeus was almost impossible.
I've come to realise the process of studying the occult is very scatterred. It seems every1 just sort of picks up random bits n bobs here and there and tries to piece things together.
You have a lot of knowledge and I value your wisdom. Idk if this is a lot to ask, but I'd like you to help guide me to the correct direction to become as knowledgable as you are currently, in these areas, if this is something you're open to.
Ask the gods for guidance on this. Thoth is perfect for this. They will know how to guide you much better than anyone else.
