Meditating on loving-kindness leads us to the highest states of realization, for loving-kindness is at the heart of high meditations such as “emptiness,” which is the unbounded, non dual, and fully awakened state of openness. The more we train ourselves to wish joy for others, the more we loosen the tightening rope of our mind’s grasping at “self” and selfish attitudes. As that happens, our negative emotions, like attachment and hatred, will subside. And the walls that we habitually erect between self and other, between “us” and “them,” between this and that, will erode, bringing us closer and closer to the true nature that we all share.
