While browsing through one of my favourite sites, I found this
page, which talks about the Japanese/Chinese Buddhist astrology.
I have several questions about this: Does this teaching (or even astrology in general) exist in Tibetan Buddhism, or is this strictly Chinese/Japanese? Further, if it is not an acceptable teaching in Tibetan Buddhism, why? Also, are there any correlations between the 28 star deities and any of the deities in Tibetan Buddhism? I've gone through the lists, and none of the Sanskrit names seem familiar to me.
I do know from my limited knowledge that these systems were used extensively by the court astrologers (e.g. Abe No Seimei) for the Tsuchimikado family in Japan, I just wonder if they exist outside of Japan and China.
