Whether people are fully aware of it or not, their lives are chiefly spent in an unceasing endeavor to increase their pleasant feelings and to avoid unpleasant feelings. This talk explores the Mindfulness of Feeling as one of the four Foundations of Mindfulness (satipatthana) and how it may be undertaken in the framework of that meditative practice aiming at the growth of Insight (vipassana). I discuss how there should first be a mindful awareness of the feelings when they arise, and how one should clearly distinguish them as pleasant, unpleasant (painful) or neutral, respectively. I then explore how this practice can be an efficient tool for breaking the chain of suffering at its weakest link.
