I studied and practiced Daoism seriously for several years before I encountered Buddhism. I did a two-year immersive (meaning I lived at a rural community with cultivators, teachers, and students, where we practiced and studied every day) training in classical Chinese medicine, Qigong and Taiji, Internal Alchemy, and Daoist meditation practices. Although I have since studied Indian yoga and Tibetan Buddhism as well, I have maintained my Daoist training and practices for over 15 years. While there are philosophical differences between these systems, personally I find no conflict: I think of them as symbolic frameworks for living well — each framework has internal consistency, and it’s best to not try to apply one framework to analyze another — but when contemplated deeply, and practiced in one’s own experience, they provide fruitful insights.
I don’t think of it as something to “believe in” or not — I think of it as something to experience and discover. I found the concept of qi easy to grasp: the interconnected flow that interacts with and influences everything. A principle of Daoist medicine and Internal Alchemy is that the outer world and the inner world reflect one another, so we can learn about our inner world — our body, organs, mind, etc. — by studying the outer world. Specifically, the constant process of transformation, how the elements interact and influence one another, is part of the cosmos, the ecosystem, the community, and our own inner environment. While this is obviously complex to understand, the more one contemplates it, the better one is able to live in harmony with the world. Everything we eat — both foods and herbs — influence our organs according to predictable patterns. So I “believe” in it because it is observable, testable, predictable.
Chinese medicine is an officially recognized form of general care in many states, including California. While western science and medicine do not accept the psychosomatic relationships between organs and emotions, or the flow of qi through the meridians, Chinese medicine can respond by saying “those are metaphors that guide treatment.” Simply think of “qi” as circulation, and consider that healthy organs lead to wellbeing. Western doctors can accept that acupuncture, cupping, and moxibustion improve circulation and reduce pain — and maybe that’s enough.
