Security is a myth.
Just as classical mythology recounts tales of the Sky god Ouranos (Uranus) who comfortably ruled the entire Universe alongside the stabilizing force of the Earth god Gaia, it was the sudden castration and rebellion led by his own son, Cronus, that ended the rulership of Ouranos, and launched his demise as top god in the hierarchy.
Uranus incites rebellion in Astrology. This sky-blue colored planet encourages us to disrupt the status quo, and revolt against the hierarchy.
