I've studied Astrology in a fair amount of depth (years ago!). It remains, more or less in the back of my mind.
It can be valuable if I'm seeking to connect to a client, understand their issues. I never bring it up unless the client does first, due to all the misconceptions.
It think an awareness of the complete natal chart (day, time year, location) is necessary for it to be a valuable too.
As for the LMT, I look to what's happening in the 8th house, Scorpio, 12 house, Neptune energies first.
Thanks so much for this information! I am currently working on the paper, but will have it posted on my website within the next couple of weeks! I would love to talk more in depth with you about it once all of my ideas are on paper. It's looking really interesting so far!!
