Tai Yang's Place in the Zi Wei Series

Tai Yang is the third of the six stars in the Zi Wei series, its palace fixed at a permanent offset from Zi Wei's own once the emperor star's position has been calculated from the birth data, the same lookup mechanism that governs Tian Ji before it and Wu Qu, Tian Tong and Lian Zhen after it in the series. Its inclusion in a series named for and led by an imperial, polar star sits naturally beside its own solar identity, since Chinese cosmological thought long paired the sun's daily rule over the sky with the emperor's rule over the state, an association Ho Peng Yoke's study of Chinese mathematical astrology traces to a much older tradition of correlating celestial and earthly order that predates Zi Wei Dou Shu by centuries.

Unlike Zi Wei itself, whose reading depends heavily on supporting company in its palace, Tai Yang carries a more independent strength drawn directly from its identity as the actual sun, waxing and waning in reading rather differently depending on the hour of birth rather than solely on which other stars share its palace. The pairing of Tai Yang with Tai Yin, the Moon, elsewhere among the fourteen stars, though the two do not sit adjacent within the Zi Wei series itself, reflects the same yang and yin polarity that organises a great deal of traditional Chinese cosmological thought beyond astrology alone.
