In light of this creation plan, the root of all human problems is that the unenlightened want to make their Paradise in this world before death, whereas under the natural laws, the situation here on earth makes this impossible. Therefore, according to God’s creation plan, man has to be content in this limited world before death, so as to make himself eligible for Paradise in the eternal world after death.

Therefore, the right and proper thing for a man to do is acknowledge and accept this law of creation, and plan his life accordingly. His sole aim in this world should be to make himself acceptable in the eyes of God so that he may be held eligible for admission into Paradise in the eternal world after death. Successful is one who has realized the eternal world of Paradise in this temporary world, who has discovered in the failures of the present world, the secret to eternal success in the next eternal world.
