From the recording Three in One and One in Three


Safe and Balanced, our movement like cars, spinning wheels.Turning and yielding is responding.Heavy weight slows your progress; stagnant, stagnant.
You study for many years and you feel confident, But you still loose to your opponent. For the mind and the body are too heavy (x2)
To become less stagnant, you must know yin & yang (x2)Yin & yang move and spin each other.
(from The Essence Of Tai Chi Chuan)
