What do O and◇mean in the arrangement of Taoist magic?

O stands for empty death; ◇ or △ means Ma Xing.

In Daoism, people pay attention to strangeness, doors and avoiding armor, which means hiding, so that under the six instruments, Jia Zi hides E, Jia Xu hides himself, Geng, Xin, Ren and Jia Yin hide Gui. For Liu Jia, every piece of armor was ten years ago and sixty years ago.

There are 10 state-owned and 12 land-owned. Starting from the first group of Jiazi, ten branches and twelve branches are combined into sixty Jiazi, which are Jiazi, Yechou, Bingyin ... Gui You; At this time, the sky is gone, and there are two earthly branches, so the two earthly branches of this group are empty, also called Liu Jiaxun Empty, Jiazi Ten Sky, JOE Ten Sky ... Jiayin Ten Ugly;

On the other hand, Ma Xing is a trinity based on the twelve branches of the earth, while Ma Xing usually indicates that there is a moving image. The definition of Ma Xing is to find the six red positions of the triad, such as Shen Shi, and then find the hedging position of Shen Zi, that is, Yin, that is, Shen Shi, Zi Shi, Ma Xing in Yin, and so on.

I hope I can help you.
