This question was sent in during our teleclass last night, but we didn't have time to answer it at the time -- so here's the question, and my answer:
I was born in July 1956. Will I have two 2nd Saturn returns because of Saturn retrograde?
In July 1956, Saturn was at 26 degrees Scorpio. Your second Saturn return is a couple years away -- but it looks like Saturn will just pass over your natal Saturn one time, in November 2014.
For those who have Saturn crossing over their natal Saturn three times (which is what happens when Saturn crosses over it while going forward, then crosses it while retrograde, then crosses over it a third time when direct again) -- it means that the experience of the Saturn return (or any transit that occurs multiple times) is spread out over a longer period of time, and may involve some more life-changing experiences, challenges, or opportunities.
I hope that answers your question -- and thanks for attending the teleclass!
