Of the bright stars that lie close to the ecliptic, Spica is virtually the only candidate for a fiducial star that is located near a sign junction, and this junction happens to be just at the center of the sidereal zodiac between Virgo and Libra. Perhaps of greater interest is that Spica is only minutes in longitude from bright Arcturus to the north. Edgar Cayce gave great importance to Arcturus as evidenced from these quotes from his readings:
“For Arcturus is the way, the door out of this system.” (2454-3)
“Not that the Sun as the center of the solar system is all there is. For the entity has attained to that realm even of Arcturus, or that center from which there may be the entrance into other realms of consciousness.” (2823-1)
“Arcturus is that which may be called the center of the universe, through which individuals pass and at which period there comes a choice of the individual as to whether it is to return to earth or to pass on to other systems. (5749-14)
“Arcturus is that junction between spheres of activity as related to cosmic force, and is that about which this particular sphere of activity rotates...” (263-15)
