One man devotes his life to the world as real and solid, worthy of his confidence.
Another man devotes his life to the world as illusion, a mirage or waking dream.
Yet another man devotes his life to God, and the world as an outpouring of love.
Yet another man devotes himself to the world as himself, intimate with all that is.
The last man knows there is no world or illusion. He devotes himself to reality.
Who are these men? They are the same man at different points on the journey home.
