Human beings are composed of three parts: essence, qi, and spirit. Among them, essence and qi are the roots, and both the original qi and essence are stored in the kidneys. Therefore, nourishing the kidneys is particularly important. The kidney is the innate foundation, with the function of storing essence, regulating water, and regulating bone and marrow. The human body grows and develops with the gradual prosperity of kidney essence until maturity. If the kidney essence is full, then the energy is abundant, the muscles and bones are strong, the steps are light and agile, and the mind is agile. With age, the body's kidney essence is consumed, and through cultivation, it can maintain the body's kidney essence, thereby achieving the goal of prolonging life.
Sit naturally and breathe in a clockwise manner, with nasal suction protruding from the abdomen and nasal exhalation concave from the abdomen. Breathe naturally and gently, and concentrate your thoughts on the lower abdomen (1.5 inches below the navel). After reaching Dantian fever or abdominal fever, with the navel as the center, use Yishou to lead the internal qi of Dantian in a clockwise direction, from left to right, and from top to bottom, with a uniform circular rotation speed of 18 circles. Then reverse and rotate in a counterclockwise direction for 18 circles as described above, and insert it into the navel Shenque acupoint. Rotate repeatedly like this, practice diligently every day, and gradually increase the number of rotations to 24, 36, 72, and 81 circles when you can freely rotate the internal qi of the elixir field.
Note that during the rotation, the upper range of rotation should not exceed the left and right rib arch edges, and the lower range should not exceed the pubic symphysis and the left and right iliac crest. The laps with less frequency should have a larger pitch, while the laps with more frequency should have a smaller pitch. The rotation of internal qi must be a regular circular movement, and the speed of movement should not be too fast. It must be closely coordinated with breathing and mind. When the internal qi cannot move freely, do not force it to move, nor do you rotate it randomly from left to right, in order to avoid the reversal of qi and deviation, which may lead to failure in practice. At the beginning of practice, it may feel difficult for the internal qi to rotate freely, but as long as you practice diligently, the internal qi can rotate smoothly and gradually gather into a ball. In the future, with the continuous enhancement of martial arts skills, this internal qi can rotate repeatedly in the abdomen with the guidance of the mind during each movement.
After practicing the above kung fu, still use the clockwise breathing method. When inhaling, the internal qi of the mind drops from the Dantian to the perineum, while relaxing the anus; When exhaling, guide the qi upwards through the Mingmen (under the second lumbar spine process) to the lower Dantian, while also cooperating with the contraction of the anus. By repeating this process repeatedly, with the operation of the Qi machine, the Dantian, Huiyin, and Mingmen can be connected into a circular ring (this method is called "Xiao Zhou Tian", also known as "Xiao Fa Lun").
Next, use your mind to rotate the internal qi in a clockwise direction (from top to bottom), from left to right, and from outside to inside in a regular circular motion. When inhaling, the qi passes through the ventral side, and when exhaling, it passes through the lumbar side (i.e. through the belt pulse). When the mind reaches the qi, the mind turns with the qi. Then, in a counterclockwise direction, rotate from right to left and from inside to outside in a reverse direction until the qi rotates freely. Rotate the inner qi along the inner side of the abdominal wall, from left to right, in a spiral circular rotation from the small abdomen upwards. After turning to the pit of the upper abdomen (i.e. the concave xiphoid process), perform a spiral circular rotation from top to bottom, once up and down, for a total of 72 times.
