"Sixteen ingots of gold" is the basic skill of China Taoist Inner alchemy. There are three versions circulating now, but the content and text are slightly different. In order to facilitate teaching, learning and research. The excerpts are as follows: "Red Wind Pit" says: "When inhaling, the gas is lifted up and returned to the navel; Swallow when you mention it, and water and fire are incompatible. " "Health cheats" said: "If you lift it, you will lift it, and the qi will return to the navel; Swallow it as soon as it falls, and fire and water will meet. " "Pulse Table" says: "Lift when inhaling, and return to the navel when inhaling. Swallow it in one breath, and the fire and water intersect. " Usually, the version of "Red Wind Pit" is circulated: "When you inhale, it will be lifted and the breath will return to the navel; Swallow when you mention it, and water and fire are incompatible. " This version, * * * sixteen words, the context is obvious, * * * is divided into two steps. The first step is to "lift it as soon as you inhale, and return it to your navel." The main idea of these eight words is to lift the anus and promote qi. Wave your hands up and inhale synchronously to "lift your anus". The process of inhaling is to return to the navel (that is, the human body goes down to the abdomen); The second step is "swallow when you mention it, and fire and water meet." Wave and inhale to "lift the anus" synchronously. The word "pharynx" has different interpretations, and I show that this Sect breaks it down into "knocking teeth and swallowing body fluid". Not pharynx essence, not pharynx. It's tongue touching teeth hitting the sea. When body fluid is swallowed, "fire and water meet", heart and kidney intersect, and fire and water ji ji.
