Aging on the Pathway of the Soul Part 3
"For the remaining years of life, there should be an increasingly strong relationship between the soul and its vehicles, leading to another crisis between the fifty-sixth or the sixty-third years. According to that crisis will depend the future usefulness of the person and whether the ego continues to use the vehicles on into old age, or whether there is a gradual withdrawal of the indwelling entity." ESOTERIC PSYCHOLOGY VOL. II by Alice Bailey.
