Sometimes in mindfulness meditation, I like to teach that we are rooted in the breathing. It is like the default. That is the place we cultivate stability and steadiness of mind – to stay in the present moment. But if some other sensation arises in the body that is more compelling, then we contentedly, relaxedly, let the attention float to that other place. We begin doing the sensation meditation in that place, in the knees, or the back, or wherever the sensations might be strong.
