Cycles of Becoming, The Planetary Pattern of Growth by Alexander Ruperti is probably one of the best books I’ve ever read on the study of cycles, phases , and patterns.
Here’s what he writes for age 56-63.
Phase 9. Possibility of 3rd birth in the Uranian cycle. Demonstration of the capacity to focus the spiritual quality of being inherent at birth, through the personality. New spiritual activities or, negatively, further crystallization of mind and feeling responses.
He goes on to write that after 63 we move towards, “conscious preparation for the afterlife….or senility”
