Everyday we use our mind and body and we depend on breathing. Do we really take care of them? Can you remember how it happened when you sprained your ankle or wrist? How the coughing became irritated? And how you were hurt by loosing your temper? These damages to yourself are all caused by the stirring mind! Whether you are able to avoid hurting depends on staying with a clear clean mind or not.
The Middle Way will bring us to proper concentration. Too much intention to relax will cause tension. Too much intention to focus will cause fatigue. Too much intention to breathe will cause pressure.
The mindfulness of a simple movement such as belly’s up and down, is like a “chain” to help us tame the mind not to wander away. But we should be patient on the taming, because the mind needs time to accustom itself to the new habit. In the beginning, try not to let the wandering go too far, and keep a clear mind on it, until they naturally come back to the “target” of mindfulness.
When we are doing the walking meditation, we are not trying to make a perfect step, but just a clear step.
