In MIDL Mindfulness Training 18/52 you further develop your perception of the four elemental qualities. As this perception strengthens and concentration develops, you intentionally bring awareness to the borders between things such as one of your hands touching the other or your body pressing against the chair or floor. As you focus on the elemental qualities at these points of touch the mind created perceptional borders start to dissolve. Insight Timer Group: MIDL Mindfulness Meditation
