Spiritual longing is a sort of loneliness for an unknown yet deeply perceived presence. Some call the presence God; some call it peace; some call it consciousness; some call it Love. It's source rests in the well of our own hearts. When we slow down, quiet the mind, and allow ourselves to feel hungry for something that we do not understand, we are dipping into the abundant well of spiritual longing. If we want to open to doors to life's love and God's peace, we have to learn how to fearlessly explore the full terrain of our human longing.
All final spiritual reference is to be the silence beyond sound. The word made flesh is the first sound. Beyond that sound is the transcendent unknown, the unknowable. It can be spoken of as the great silence, or as the void, or as the transcendent absolute.
