This tenderness for life, bodhichitta, awakens when we no longer shield ourselves from the vulnerability of our condition, from the basic fragility of existence. It awakens through kinship with the suffering of others. We train in the bodhichitta practices in order to become so open that we can take the pain of the world in, let it touch our hearts, and turn it into compassion.
Our being is silent, but our existence is noisy. Yet when our noisy actions stop, there is a ground of silence always there. Contemplatives must be in contact with that ground and communicate from that level to keep silence alive for other people.
