5.52

The sun and moon losing their degrees (日月失度: the last character is pronounced *tu* + *gu* [= *dù*]; according to Master Qingcen: "The sun is the essence of extreme yang, completing one circuit of the heavens in one year; the moon is the essence of extreme yin, completing one circuit of the heavens in one month"; the *Jinkui jing* says: "The moon governs distress and calamity, while the sun governs fortune and virtue; therefore the moon is the extraordinary punisher and the sun is the extraordinary benefactor"; usually at the winter solstice the sun is at the twenty-first degree and one quarter of the Dipper [Nandou]; at the spring equinox the sun is at the fourteenth degree of Kui; at the summer solstice the sun is at the twenty-sixth degree of Dongjing; and at the autumn equinox the sun is at the second degree and one quarter of Jiao; any divergence from this constitutes losing their degrees).
