Immortal People Cannot Avoid Warblers.

There are only three things in the world: spirit, energy and essence. Therefore, the three things are related to each other. If they go along, they will become adults, and if they go against them, they will become immortals. What is smooth? Two are born, two beget three, and three beget all things, so the void turns into spirit, the spirit turns into qi, the qi turns into essence, the essence turns into form, and the form becomes human. What is inversion? All things contain three, three returns to two, and two returns to one. Those who know this way can subdue their hearts, reduce desires and nourish essence, accumulate essence to transform qi, refine qi to combine with spirit, refine spirit to return to emptiness, refine emptiness to return to form.
