We are part of nature and its cycles. If we go against natural cycles sickness results, so it is in our best interest to follow the way of nature. This is the meaning of Tao. This is an excellent video discourse and demonstration overviewing principles of Qi, Tao, Qigong, acupuncture and Chinese herbs. Cultivating understanding and practice in the way Qi flows, and knowing how to regulate it correctly, one should be able to live a healthy, long life.

Rules and Judgement, Su Wen Ch.70
Judgment [lun cai] and mind [zhi yi] must be based upon laws and rules. If one follows the classics, observing the calculations and accordingly, practicing [medicine] with due reverence to these rules, will be of benefit and set an example for all humankind. If the way is carefully observed, myriad diseases can be cured. Qi and Blood will assume a proper balance, and the Mandate of Heaven will last long.
Pertaining to Rules and Judgements
• If one punishes where there is no transgression, this is a great error.
• If one rebels against the grand norms of nature, True Qi cannot be restored.
• If a practitioner treats a repletion as if it were a depletion, if s/he considers evil Qi as if it were true Qi, and if s/he [applies needles] disregarding what is right to do, plunders Qi, and in that, removes proper Qi [of the patient].
