In tonglen practice, when we see or feel suffering, we โฏbreathe in with the notion of completely feeling it, accepting it, and owning it. Then we breathe out, radiating compassion, lovingkindness, freshness - anything that encourages relaxation and openness.โฏ So you're training in softening, rather than tightening, your heart. In this practice, it's not uncommon to find yourself blocked, because you come face to face with your own fear, resistance, or whatever your personal "stuckness" happens to be at that moment.

Pema ChodronLearning how to be kind to ourselves, learning how to respect ourselves, is important. The reason it's important is that, fundamentally, when we look into our own hearts and begin to discover what is confused and what is brilliant, what is bitter and what is sweet, it isn't just ourselves that we're discovering. We're discovering the universe.
