The efficient cause of this material world, manifested with its many varieties as the original tree, is You, O Lord. You are also the maintainer of this material world, and after annihilation You are the one in whom everything is conserved. Those who are covered by Your external energy cannot see You behind this manifestation, but theirs is not the vision of learned devotees.
