Recognizing and maintaining the natural purity and clarity of the mind is the key to mental health:

“The accomplished ones of ancient times advised people to guard themselves against zei feng, disease-causing factors. On the mental level, one should remain calm and avoid excessive desires and fantasies, recognizing and maintaining the natural purity and clarity of the mind. When internal energies are able to circulate smoothly and freely, and the energy of the mind is not scattered, but is focused and concentrated, illness and disease can be avoided.

Equalimity within and compassion without is the way for personal wellness:

“Previously, people led a calm and honest existence, detached from undue desire and ambition; they lived with an untained conscience and without fear. They were active, but never depleted themselves. Because they lived simply, these individuals knew contentment, as reflected in their diet of basic but nourishing foods and attire that was appropriate to the season but never luxurious. Since they were happy with their position in life, they did not feel jealousy or greed. They had compassion for others and were helpful and honest, free from destructive habits. They remained unshakable and unswayed by temptations, and they were able to stay centered even when adversity arose. They treated others justly, regardless of their level of intelligence or social position.”

The female and male reproductive physiology of TCM and the infertility process:

Huang Di asked, “When one grows old, one cannot bear children. Is this due to heredity or to the loss of one’s procreative energy?”

Qi Bo answered, “In general, the reproductive physiology of woman is such that at seven years of age her kidney energy becomes full, her permanent teeth come in, and her hair grows long. At fourteen years the tian kui, or fertility essence, matures, the ren/conception and chong/ vital channels responsible for conception open, menstruation begins, and conception is possible. At twenty-one years the kidney energy is strong and healthy, the wisdom teeth appear, and the body is vital and flourishing. At twenty-eight years the bones and tendons are well developed and the hair and secondary sex characteristics are complete. This is the height of female development. At thirty-five years the yangming/stomach and large intestine channels that govern the major facial muscles begin to deplete, the muscles begin to atrophy, facial wrinkles appear, and the hair begins to thin. At forty-nine years the ren and chong channels are completely empty, and the tian kui has dried up. Hence, the flow of the menses ceases and the woman is no longer able to conceive.

“In the male, at eight years of age the kidney energy becomes full, the permanent teeth appear, and the hair becomes long. At sixteen years of age the kidney energy is ample, the tian kui is mature, and the jing is ripe, so procreation is possible. At twenty-four years the kidney qi is abundant, the bones and tendons grow strong, and the wisdom teeth come in. At the thirty-second year the body is at the peak of strength, and functions of the male are at their height. By forty the kidney qi begins to wane, teeth become loose, and the hair starts to fall. At forty-eight the yang energy of the head begins to deplete, the face becomes sallow, the hair grays, and the teeth deteriorate. By fifty-six years the liver energy weakens, causing the tendons to stiffen. At sixty-four the tian kui dries up and the jing is drained, resulting in kidney exhaustion, fatigue and weakness. When the enrgy of all the organs is full, the excess energy stored in the kidney is excreted for the purpose of conception. But now, the organs have aged and their energies have become depleted, the bones and tendons have become frail and stiff, and movements are hampered. The kidney reservoir becomes empty, marking the end of the power of conception.”

The abundance of jing, protecting of vitality (minerals) in five internal organs is the key to prolonged sex life and fertility:

Huang Di remarked, “I notice, however, that some people, even though they are quite elderly, can still conceive.”

Qi Bo replied, “This is because these individuals inherited an unusual abundance of jing and also realized how to lead their lives properly and protect their vitality. At sixty-four and forty-nine, for males and females respectively, these individuals still have excess kidney energy as well as qi and blood, so they still have the capacity to procreate. However, men past the age of sixty-four and women past forty-nine have normally lost this ability.”

Huang Di asked, “ If a wise one who follows the Tao is over one hundred years of age, can he or she still retain the ability to procreate?”

Qi Bo answered, “Yes, it is possible. If one knows how to live a correct way of life, conserves one’s energy, and follow the Tao, yes, it is possible. One could procreate at the age of one hundred years.”

Doing Qi Gong is the core part of living longevity :

Huang Di inquired, “I’ve heard of people in ancient times, spoken of as the immortals, who knew the secrets of the universe and held yin and yang, the world, in the palms of their hands. They extracted essence from nature and practiced various disciplines such as Dao-in and Qi Gong, and breathing and visualization exercises, to integrate the body, mind and spirit. They remained undisturbed and thus attained extraordinary levels of accomplishment. Can you tell me about them?”

Qi Bo responded, “The immortals kept their mental energies focused and refined, and harmonized their bodies with the environment. Thus, they did not show conventional signs of aging and were able to live beyond biological limitations.

There are 4 types of immortals mostly inspiring :

1. “Not so long ago there were people known as achieved beings who had true virtue, understood the way of life and were able to adapt to and harmonize with the universe and the seasons. They too were able to keep their mental energy through proper concentration.

2. “These achieved beings did not live like ordinary humans, who tended to abuse themselves. They were able to travel freely to different times and places since they were not governed by conventional views of time and space. Their sense perceptions were supernormal, going far beyond the sight and hearing of ordinary humans. They were also able to preserve their life spans and live in full health, mush as the immortals did.

3. “There was a third type of person, known as the sage. The sages lived peacefully under heaven on earth, following the rhythms of the planet and the universe. They adapted to society without being swayed by cultural trends. They were free form emotional extremes and lived balanced, contened existence. The outward appearance, behavior and thinking did not reflect the conflicting norms of society. The sages appeared busy but never were depleted. Internally they did not overburden themselves. They abided in calmness, recognizing the empty nature of phenomenological existence. The sages lived over one hundred years because they did not scatter and disperse their energies.

4. “A fourth type were natural people who followed the Tao and were called naturalists. They lived in accordance with the rhythmic patterns of the seasons: heaven and earth, moon, sun, and stars. They aspired to follow the ways of ancient times, choosing not to lead excessive lifestyles. They, too, lived plainly and enjoyed long life.”

The above 4 types of immortals have been the mentals for all Daoists practitioners and Master Chinese Medicine Doctors over the 5000 years Chinese history. It has been more relevant for us today to study and gain insight for the wellbeing of all.
