John Welwood said this quote

Awareness born of love is the only force that can bring healing and renewal. Out of our love for another person, we become more willing to let our old identities wither and fall away, and enter a dark night of the soul, so that we may stand naked once more in the presence of the great mystery that lies at the core of our being. This is how love ripens us -- by warming us from within, inspiring us to break out of our shell, and lighting our way through the dark passage to new birth.
