Man is a broken seed, yet to be a tree.
The stone is God asleep, in deep sleep. It is completely a seed; there is no chance of it breaking from any angle.
Man is not a tree, but a broken seed. There is a fine crack somewhere, but has not yet become a tree, nor is he a stone. Man is in between somewhere on a journey. Man is traveling; or it is more appropriate to say that man is a journey; or even better, man is a milestone on the path.
The seed has set out on the journey to be a tree. He has just begun to look through the crack and is beginning to sprout. Man is the sprout, a sprouted seed. He has the potential to become a tree. But, he is not one, yet.
