Silence is where we learn to listen, where we learn to see. Holding silence, being held by stillness, people go alone to the wilderness "to stop and see", to renew their vision, to enter the mind ground, to hear the truth, to return to the knowledge of the extensiveness of self and the truth of no self. One seeks solitude to know relatedness. There the unknown, the unarticulated, the unpredictable, the uncontrollable appear as protectors of the present.
Compassion is an aspect of Divine love that melts all defenses and resistance when anyone's suffering is really seen. There is nothing the personality can do to create compassion, but when we are willing to be completely open and truthful about whatever we are truly feeling, it arises naturally and soothes our hurt. (We could say that truth without compassion is not really truth, and that compassion without truth is not really compassion.) The Divine love that seeks to express itself in the world through us is a powerful force that can break through all of the old barriers and untruths that have accumulated in us.
