Good Vibrations

The middle way is, in fact, the vibration between extremes.
A resonance, rather than a blinkered middle ground.
To tread the middle path requires intimacy with all the edges, and beyond.
Working in extreme territory will often give you the energy to leap to the next stage.
The path is like a series of stepping stones across a river.
The distance between the stones gradually increases, so your training has to be wholehearted and thorough otherwise you wont manage the next challenge.
It is well-nigh impossible to miss a stage out.
There is a Tai Chi saying: "The next stage is always the most difficult".
A student once stupidly said to me, "I'm really glad I didn't practice what you showed me last time because it has all changed now".
If the work is alive it will always be changing and developing, in form and energy. The students have to be constantly vigilant to these changes. Even if the Form looks exactly the same, try to feel how you, your teacher and the energy have subtly moved on.
Accept the challenge of the unknown rather than weakly clinging to the known.
This is the key to immortality.
