First, you don't understand yin and yang.

Second, you don't understand heaven and earth

Thirdly, Leifa is divided into existentialism and a kind of near existentialism.

Fourth, it is Yin and Yang who can help, not Lei Fa.

Fifth, it is teaching, not home. There is no Leifa at home, only teaching. God is a sect, not a home.

Sixth, write a book if you can. I'm afraid everyone has written it, but you can't understand it. There are many argots in Taoist Dan Jing, which take a long time to learn and may not be understood.

Seventh, Leifa is an inner alchemy, which is nothing more than immortality. External alchemy is the source of immortality. If you don't know the world of Yin and Yang, you can't fix it.

It doesn't matter if you want to learn from the Great Liu Ren, but you should know that divination is mainly based on the Book of Changes, and it is constantly developing. If you learn Neidan, you might as well learn the Book of Changes.
