i can only answer how i deal with this i am good at mental arithmetic and can make all the adjustments in my head.yes there are two different ephemeris .and two different interpretations of a chart in fact i believe a different interpretation from each astrologer.how we can reconcile two different systems with two different interpretations most people dont .a simple thanks but no thanks is the usual response.some will be curious but not many as its a lot of work.
Tell me Mulaian what inventions that were done were not a lot of work? How many times did Edison try to make a light work before it did? Literally hundreds. Perhaps thousands of times. You may have noticed that i have not said you are wrong in the eastern outlook nor have i said i am right in the western approach. Merely that there are differences and similarities. My goal is to find a feasible link that ties these two forms together. Perhaps it will be work for our predecessors but we can lay the foundation of that quest.
We can start out with the premise that Sri Yukteswar had. That is the procession of the equinoxes which he called the Yugas that affect mankind in general. There is further study of this phenomena in The book the Initiation by Elizabeth Haich. However without reading a lot we can use the knowledge we have of the two systems to compare notes.
First of all any emphemeris that i know of shows not the eastern appraoch but rather the western approach. Do you know of a ephemeris that shows the postion of the stars in there correct position taking into acoount the procession of the equinoxes? Or all ephemeris books showing the postion of the signs in a totally Sun centered astrology? If you know a book that tells me the postion of the planets according to the position of the planets today, that takes into account the procession of the equinoxes, please tell me. i think that it would be harder to have such a book since the position of the planets with regards to the signs are changing over time in more than one way. You say in your post that there are "two different ephemeris" Do you mean in your head, because you do the calculations, or do you mean there literally are two different books?
