How can the seed know that by dying in the soil it will become a great tree? It will not be there to witness the happening. How can the seed know that one day, if it dies, there will be great foliage, green leaves, great branches, and flowers and fruits? How can the seed know? The seed will not be there. The seed has to disappear before it can happen. The seed has never met the tree. The seed has to disappear and die. Only very few people have that much courage. It really needs guts to discover truth. You will die as yourself. You will certainly be born.
