It is important to have a secret, a premonition of things unknown. It fills life with something impersonal, a numinosum. One who has never experienced that has missed something important. We must sense that we live in a world which in some respects is mysterious; that things happen and can be experienced which remain inexplicable; that not everything which happens can be anticipated. The unexpected and the incredible belong in this world. Only then is life whole. For me the world has from the beginning been infinite and ungraspable.
The fitness of our hearts and thoughts to receive God's spirit is like that of violin strings. If they are properly tuned, in harmony with one another, then the touch of the bow produces beautiful music. If not, then there is only discord. Whenever our hearts are truly ready to receive God's spirit, they will produce heavenly airs and joyous harmonies -- both in this life and in the spiritual world.
