Notice the 2 YODS (symmetry of aspects in green dotted lines)
1) Jupiter (the enobling force according to Cayce's Reading.....see the reading under Astrology Link threads)
2) Jupiter connects to Sun & Mercury, then again to Neptune
3) The 2nd Yod is still more intriguing, considering we know he was indeed Leonardo.....because it's to:
.................Uranus,/eccentric genius,unique in every way
Neptune & the mind (Mercury)...................
The Sidereal Chart is because Edgar Cayce in trance spoke of the positions & signs, as the TRUE constellation,,.....as the ancients did.
Hence, the Sun becomes, in the Sidereal position, one of Sagittarius,
not Capricorn. or the true Constellation at birth.
