[The only reference to date found to directly reference any sort of physical manifestations of the Tao where the translated term, "antics," seems to indicate an adverse view of a martial art and the Taoist beliefs. Yet, it does not actually say one way or another whether this system of physical activity does or does not relate to Tao. It would be interesting to have found further reference to martial arts/fighting arts and the way of Tao, etc.
Then again, the reference to both "mystic" and "recondite" may allude to more than the quote as it stands alone. After all recondite, meaning: "incomprehensible to one of ordinary understanding or knowledge," does have possibility that the translator not having any knowledge or understanding of the art of Kung Fu could not elucidate further as to its relation to Tao and Taoist beliefs. The term does mention a type of wisdom that is both abstruse and "profound" in its meaning and thus relations.
This term also indicates that such knowledge is best known by the "experts" which in this case should/could involve one or many who are experts in Kung Fu and also at least knowledgeable/understanding of Taoist beliefs and Taoism.]
