I have recently made the discovery that increasing the amount of time I spend on walking meditation does not have the same impact on the movements as increasing the amount of time I spend on breath meditation. In fact, it does not seem to have any impact at all.
Because of the body movements, I got the impression that meditation retreat is simply something I have to go without. Now that I have made this discovery, I am going to experiment with doing a 1 day home retreat that emphasizes walking meditation and will report back here.
