Bruce:

“In the yin yang symbol, there is a white spot on the black half, and a black spot on the white half. In JKD, Yang (firmness) should be concealed in Yin (gentleness) as Yin is concealed within Yang. Thus, a JKD man should be soft, yet not yielding; firm, yet not hard. The curved arrows surrounding the Yin Yang symbol represent not only the harmonious interplay of Yin Yang but also the interchangeability of opposites.”

The Chinese characters that Bruce Lee wrote around the Yin Yang symbol and arrows are a phrase he authored and used to represent his philosophy, which translated read:
“ Using no way as way, Having no limitation as limitation”.
