Bruce Lee: Likeness

“Be like water making its way through cracks. Do not be assertive, but adjust to the object, and you shall find a way around or through it. If nothing within you stays rigid, outward things will disclose themselves.

Empty your mind, be formless. Shapeless, like water. If you put water into a cup, it becomes the cup. You put water into a bottle and it becomes the bottle. You put it in a teapot, it becomes the teapot. Now, water can flow or it can crash. Be water, my friend.”

“Love is like a friendship caught on fire. In the beginning a flame, very pretty, often hot and fierce, but still only light and flickering. As love grows older, our hearts mature and our love becomes as coals, deep-burning and unquenchable.”

“Now I see that I will never find the light
Unless, like the candle, I am my own fuel,
Consuming myself.”

“The happiness that is derived from excitement is like a brilliant fire — soon it will go out.”

Context: The happiness that is derived from excitement is like a brilliant fire — soon it will go out. Before we married, we never had the chance to go out to nightclubs. We only spent our nights watching TV and chatting. Many young couples live a very exciting life when they are in love. So, when they marry, and their lives are reduced to calmness and dullness, they will feel impatient and will drink the bitter cup of a sad marriage.

“Instead of dedicating your life to actualize a concept of what you should be like, ACTUALIZE YOURSELF.”

Bruce Lee

Source: Striking Thoughts (2000), p. 44
Context: Concepts vs. self-actualization. — Instead of dedicating your life to actualize a concept of what you should be like, ACTUALIZE YOURSELF. The process of maturing does not mean to become a captive of conceptualization. It is to come to the realization of what lies in our innermost selves.

“If nothing within you stays rigid, outward things will disclose themselves. Moving, be like water. Still, be like a mirror. Respond like an echo.”

Context: Flow in the living moment. — We are always in a process of becoming and NOTHING is fixed. Have no rigid system in you, and you'll be flexible to change with the ever changing.

Still, be like a mirror. Respond like an echo.

“The perfect way is only difficult for those who pick and choose. Do not like, do not dislike; all will then be clear. Make a hairbreadth difference and heaven and earth are set apart; if you want the truth to stand clear before you, never be for or against. The struggle between "for" and "against" is the mind's worst disease.”

Bruce Lee

In "The Tao of Jeet Kune Do" by Bruce Lee (1975, compiled and published posthumously) and also in Striking Thoughts: Bruce Lee's Wisdom for Daily Living (2000) edited by John Little, this is attributed to Lee, perhaps because it was found in his notes, but it is also quoted in precisely this form, from what appear to be translations of Taoist writings in The Religions of Man (1958) by Huston Smith. It is actually from Xinxin Ming, by the Third Chinese Chan [Zen] Patriarch Sengcan.

“When asked what the difference between a karate punch and a kung-fu punch was during his first U. S. screen test in 1965, Bruce Lee replied, “Well, a karate punch is like being hit by an iron bar—whack! A kung-fu punch is like being hit by an iron ball swung on an iron chain with an iron ball attached to the end—it goes WHANG!—and it hurts inside.” Then he stood up and showed exactly what that might look like in a flurry of hands and feet moving so fast they blurred.”

“You know what I want to think of myself? As a human being. Because, I mean I don't want to be like "As Confucius say," but under the sky, under the heavens there is but one family. It just so happens man that people are different.”
