The difference between the internal and external energies of the Supreme Personality of Godhead is that in the internal energy, or in the spiritual world, all the opulences are undisturbed, whereas in the external or material energy, all the opulences are temporary manifestations. The Lord’s supremacy is equal in both the spiritual and material worlds, but the spiritual world is called the kingdom of God, and the material world is called the kingdom of māyā. Māyā refers to that which is not actually fact. The opulence of the material world is a reflection. It is stated in Bhagavad-gītā that this material world is just like a tree whose roots are up and branches down. This means that the material world is the shadow of the spiritual world. Real opulence is in the spiritual world. In the spiritual world the predominating Deity is the Lord Himself, whereas in the material world there are many lords. That is the difference between the internal and external energies. The Lord says that although He is the predominating factor of the internal energy and although the material world is sanctified just by the water that has washed His feet, He has the greatest respect for the brāhmaṇa and the Vaiṣṇava. When the Lord Himself offers so much respect to the Vaiṣṇava and the brāhmaṇa, how can one deny such respect to such personalities?
