But nowadays, since we know entire charts accurately, we are behooved to do a larger analysis. My spouse and I have very high Moon compatibility, but my lagna is 12th to hers, since I'm Aries rising and she's Taurus rising. So, there are problems between our charts that are serious problems. If we just looked at the Moon compatibility, since it's in the 80's range, things would look rosy. So don't be turned off at all, but rather, I hope I've helped you a little.
Many astrologers currently use both systems simultaneously.
I do not. I have never learned Western Jyotish. I think the Zodiac is incorrect, personally. But, then, I've never tasted it really, I'll give you that. In my Western Chart, there is Taurus rising with Sun, Venus and Mercury.
