Progressed aspects reliably indicate when an event will happen.

"It is not a difficult matter because progressed planets so reliably indicate the time of formation of temporary stellar aerials across the astral body, which pick up and deliver new astral energy to definite groups of stellar cells - to accurately predict about when...an event will happen.

But it is far more difficult to determine its importance, how fortunate or unfortunate it will be or the specific event."

'Life presents a series of problems to each individual. There is always a best course of action and a best mental attitude under any condition that may arise.

The Hermetic System of Astrology discovers them and makes them plain".
