We explore the core intention of metta practice, to bring kindness, warmth, and care to every moment and every being. We examine how metta practice develops further steadiness (samadhi), how it helps us to lead with the heart and work with what stands in the way of the open, kind heart. As we practice further, we open increasingly to the radiance of our hearts and our being. We keep training, and we bring our metta practice into the world, where it is deeply needed. We close with two stories of metta practice in the world in challenging situations.
