Thunder-Conjuring Triune Sigil

⻗ (Rain) + 斬 (Cleave/Zhan) + 聻 (Zhi) → Yǔ Jiàn Ěr
This talisman is the hidden sacred name of Emperor Ziwei , the supreme deity in Taoism, hence known as the "Ziwei Taboo" .

Its structure symbolically aligns with the "Three Powers" ( San Cai) of cosmic order:

"⻗ (Rain)" represents Heavenly Qi descending 

"斬 (Cleave)" embodies the mortal realm's ritual blade

"聻 (Zhi)" signifies the laws of the underworld 

This design resonates with the generative logic in the Daodejing (Chapter 42):
"The Dao gives birth to the One;
The One gives birth to the Two;
The Two gives birth to the Three;
The Three gives birth to all things."
