Primordial Yang Talisman Scripture

With a total of just over 140 characters, the entire text is in rhymed four-character verses, and its meaning is rather abstruse and obscure. It contains lines such as "Blood nourishes the five viscera, the divine talisman aligns with the Fire Lord; brain is infused with precious fluid, the embryo rises to assist the true self; the heart and mind remain unshaken, spirit stirs the Gate of Vitality"—phrases that appear to be mnemonics for sexual cultivation and nourishment practices.
