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.
Silence has many dimensions. It can be a regression and an escape, a loss of self, or it can be presence, awareness, unification, self-discovery. Negative silence blurs and confuses our identity, and we lapse into daydreams or diffuse anxieties. Positive silence pulls us together and makes us realize who we are, who we might be, and the distance between the two. Hence, positive silence implies a choice, and what Paul Tillich called the "courage to be."
