Taoism, why worship 36 and 72 ~?

Originated from the ancient philosophy of Yin and Yang, especially Yi-ology;

According to the method of yarrow divination, six are old yin, seven are shaoyang, eight are shaoyin and nine are Lao Yang. So in Zhouyi, six represents yin, nine represents yang, and so does thirty-six. Shao Zi has a saying: "When it is dry, it is a hole in the moon, and when it meets thunder, it will see the roots of heaven. Between the Tiangen Grottoes, the thirty-six palaces are all spring. " The explanations of these 36 schools are different, but they are all inseparable from the word "Yi". As for seventy-two, the ancients thought it was a fraction of yin and yang of heaven and earth, so there were twenty-four solar terms and seventy-two seasons in a year.

Of course, these theories themselves correspond to astronomical geography and climate, so I won't say much here.

As for the pure positive number of 8 1 and 99, the positive number is extremely high and the change is poor, and the anode perineum. If it changes to the extreme, it will lead to regret, just as Liu Yi said that Kang Long had regrets. The seventy-two changes are the changes of eight small yin and nine yang. Small yin wants to be pure yang, and nine yang raises small yin, which complement each other. So 72 instead of 81.

Maybe the landlord will ask, 36 is the number of 66, Lao Yin, why use it? The reason is very simple, extremes meet, yin gives birth to yang, winter goes and spring comes. Unlike the number of 99, it is extremely gorgeous and ushered in the killing of Xiao. In winter, it is necessary to have the number of 49, not to mention the number of 66, and there is yang in the yin. Of course, this number will not be very fierce.
