Disappointments in love, even betrayals and losses, serve the soul at the very moment they seem in life to be tragedies. The soul is partly in time and partly in eternity. We might remember the part that resides in eternity when we feel despair over the part that is in life.
In the fifteenth century, Marsilio Ficino put it as simply as possible. The mind, he said, tends to go off on its own so that it seems to have no relevance to the physical world. At the same time, the materialistic life can be so absorbing that we get caught in it and forget about spirituality. What we need, he said, is soul, in the middle, holding together mind and body, ideas and life, spirituality and the world.
