Robert Blaschke’s book series, volume one, approaches secondary progression from an esoteric Christianity, eastern mysticism, Theosophy angle as the “descent of Spirit into matter.” He notes Charles E.O. Carter’s nativity rule “that no direction can bring to pass what is not shown in the nativity. Exceptions to this are virtually non-existent.”
The “spiritual goal of life” technique is timed to the third secondary progressed Moon conjunct natal Moon near age 82. It can be viewed as “containing the spiritual aspirations to be attempted during this life.” [Section in paperback located on page 82.] Blaschke calls it the “missing second bookend.”
Checking it out on natal: both ends feature Venus in hard aspect to the bigger lights (Jupiter, then Sun). Less obvious: Pallas.
