Looking at things from a Tao perspective can be useful in some respects, but on a practical level, it is rather vague! If you want hard facts — the right and wrong ways of doing things — we need to drill down into particulars. As soon as we do, we leave the Tao and enter the realm of Yin and Yang — essentially ‘things’ and ‘non-things’. (In Buddhist thought this is often called Duality or the realm of ‘phenomena’.) In Japanese, Yin and Yang become In and Yo. This concept of two complimentary parts making up the whole is manifested in countless ways, for example Go and Ju (Hard and Soft) from Goju Ryu karate.
