The word durvibhavya means inconceivable by our tiny brain, and vibhakta-viryah means divided in varieties of potencies. This is the right explanation of the display of creative energies in the material world. We can better understand the mercy of God by an example: a government state is always supposed to be merciful, but sometimes, in order to keep law and order, the government employs its police force, and thus punishment is meted out to the rebellious citizens. Similarly, the Supreme Personality of Godhead is always merciful and full of transcendental qualities, but certain individual souls have forgotten their relationship with Krsna and have endeavored to lord it over material nature. As a result of their endeavor, they are involved in varieties of material interaction. It is incorrect to argue, however, that because energy issues from the Supreme Personality of Godhead, He is the actor. In the previous verse, the word nimitta-matram indicates that the Supreme Lord is completely aloof from the action and reaction of this material world. How is everything being done? The word inconceivable has been used. It is not within the power of ones small brain to comprehend; unless one accepts the inconceivable power and energy of the Lord, one cannot make any progress. The forces which act are certainly set up by the Supreme Personality of Godhead, but He is always aloof from their action and reaction. The varieties of energies produced by the interaction of material nature produce the varieties of species of life and their resultant happiness and unhappiness.
