The word 'heart' can refer to an emotional bond between people, and also to the precious faculty of empathy, an 'open heart', which means sharing the feelings of another and includes an outflow of goodwill towards our fellow humans and all life forms. This, of course, is what the Dalai Lama refers to when he says "my religion is kindness", and is closely related to the ability to feel compassion.
Eckhart TolleIf you keep your attention in the body as much as possible, you will be anchored in the Now. You won't lose yourself in the external world, and you won't lose yourself in your mind. Thoughts and emotions, fears and desires may still be there to some extent, but they won't take you over.
Eckhart Tolle
