The BEETLE is a symbol of the SUN (or more-so its DUNG), be it in Cancer or Scorpio, I used the "vehicle analogy" to highlight the ecliptic path and the actions behind the creature.
I quickly viewed the link to astrology and yes, what I have presented here, is well known - to those who see.
The 7 Rishis as referring to "SHINE" is also equated to the CHAKRA, also thought of as centres of light.
The ROSE is but a symbol of these Chakra centres. Think of the ROSICRUCIANS (rose - cross). Hinduism is the last residues of the original archaic beliefs. It is still encoded in the current major religions, just a bit more covertly. This is why we find various codes within the cards. It is a practice to maintain the truth.
In the Bible, St John refers to 7 Churches, and these too may be equated to Chakras.
BUT... and this can lead you astray. Sometimes, possibly to hide codes from those with keen eyes, the Chakras my be represented in various numbers - up to nine (nine worlds). However, seven was considered a convenient number, based upon sacred geometry and number. It fitted well within scripture.
First there was LIGHT. A DOT. A compass point. A Chakra.
The Pleiades upon Fergus Hall's Fool equates to eight pebbles, in total. How I stumbled upon the association with the cluster of Pleiades, is that, in Egypt, at Abusir, the exact layout of the Pleiades cluster can be seen, in the form of pyramids. The three great pyramids, being Orion's belt, direct one's eye to Pleiades via Taurus.
You can not tie your mind up with too much, so called, facts. Each culture has their own fable to tell, in regard to their observed world. And each victor rewrites them. You have to take notes, speculate, and trust your intuition.
The Greeks equate the Pleiades as being the seven virgins and stories of lust and intrigue prevail. However, there is a clue to the clusters possible true archaic nature and that is in its astrological observance at a particular period of the year, where it is said that it foretells of coming rain. I'm seeing the beginning of the warning given to Noah, here, and I am also seeing the ARK as the Pleiades, themselves. The basket of Moses, the whale of Jonah etc, which ferries the sun across the Milky Way, at the nexus points, of by the way, are indicated by the twin serpents perched either side of the sun disk.
The High Priestess, I am considering, is also the WOMB that assists the SUN (Fool). The Magician may be building the Ark or furbishing the fool with the necessary tools. It's all fun, Be creative and expand your mind.
