These are the final 4 in the set of 10 images that represent the planetary spheres of the Qabalah tree of life (also known as the Sephirot or Telesmic Images). Below you can see my drawing for the 7th planetary sphere on the Tree of Life, which corresponds the morning star of Venus.
Hod is the 8th sphere on the Qabalah Tree of Life. It corrresponds to letters, logic and the Logos of the Stoics.
Yesod is the 9th sphere, it corresponds to the imagination and fantasy. This is the penultimate planetary sphere, very close to the physical world and almost touching it.
Malkuth represents our manifest reality and nature all around us here on Earth. This is the final 10th sphere and the end of the Qabalah journey known as the Lightning Flash.
