Please, I need some clarification about massaging our kidneys, tail bone, and top of the hands. In the course Chunyi very briefly says what is the benefit of massaging each part, however it's not clear to me how long the massage should last, and how exactly to do it.
Besides, is it equally beneficial to massage the parts (hands, ears, tail bone, etc) any time, even without having done the meditation before?
Thank you!
