Life is hard to come by! Every life is born out of the boundless, beginningless and endless vastness of the universe, and you, he or she, appear as a human being among all living beings, how difficult it is! From the moment we are born, we have such an exquisite and complete combination that has not been found yet: the organic cooperation of the internal organs and meridians, the limbs and bones, the five senses and seven orifices, the skin couples, etc., and the highly sophisticated completion of various sensory, distinguishing and thinking functions such as color (vision), sound (hearing), fragrance (smell), taste (tongue), touch (skin sense) and law (brain). Under the education and inculcation of family, school and society, we gradually form our own outlook on life, worldview and values, and communicate with nature, family and society in a thousand forms, materially and spiritually, to pass on life, adapt to nature and serve society. After a hundred years, we return to nature as a billet of yellow earth, melting into the boundless universe with the nature of a drop in the ocean. We have to be grateful from the bottom of our hearts for the love of God, the hardship of our parents in giving birth to us, and the wisdom and greatness of our country in educating and training us to become adults. For this reason, we must be grateful for this rare life in this life, treat this rare life well, treat this hard-won priceless treasure from diet and living, spiritual and emotional, spiritual and physical cultivation and other multi-level comprehensive management, and gradually achieve a dynamic balance and harmony between individuals and nature, individuals and society, individuals and families, and individuals’ psychology and physiology in an all-round and multi-dimensional way, and finally obtain a truly complete health. With this as the foundation, we can have a strong body and abundant energy, so that our life, which is like a horse passing by, can make its due contribution, play its due role and shine its due light in the long river of the universe!
