Bhairitu, I didn't attend that ayurveda class. But as I recall that conference might have been the last ACVA conference in the Seattle metropolitan area. After that, I didn't attend any more conferences by ACVA because they started holding them in Sedona, AZ and in Hawaii. They became too expensive for me.
When I came back to California in 2004, I started attending the conferences held by Sanjay Rath and his group. Although a little different from KN Rao's methods, I enjoyed those classes he presented as well, But, for some reason or the other, Rath had a fallout with his group in California and his conferences were no longer held. If I can find another jyotish conference here in California, I'll attend it to keep up with the recent developments in jyotish analysis and concepts. If you know of one, please let me know.
