This morning, sitting in the quiet house, I remembered Ruth's 'Vow Hour' instruction that she got from her zen training.
It's very simple. You vow to sit perfectly still for the whole duration of the meditation. If one hour seems too daunting, you can shorten the duration. The main thing is to commit to the stillness for however long you chose to sit.
30', I sat, not moving at all. Body freed from the possibility of nervous restlessness, there was ample space for breath to come and go, and physical sensations to be felt, and sounds to be heard, and thoughts to be noticed.
Small vow, big reward . . .
