So long we are in the material world, controlled by the external, material energy, there is no possibility of unity. That is not possible. Because, prakṛteḥ kriyamāṇāni guṇaiḥ karmāṇi sarvaśaḥ. In prakṛti, material nature, there are three different qualities: goodness, passion and ignorance. So the all the varieties of life, they are under the control of the material nature, and therefore you see varieties of life. Varieties. There are three qualities. You multiply three into three, it becomes nine. And if you multiply nine into nine, you become . . . you see eighty-one. So therefore all these varieties of life, they are being controlled, because . . . not controlled. He accepts to be controlled. Prakṛti does not want . . . nature does not want to control you.
Just like police force. Police force is not meant for controlling you. But when you accept to be controlled by police, when you become a criminal, then police force controls you, not that police force is made by the government unnecessarily to control you. No. He's to help you. Government has arranged policeman in every crossing. They are wandering in the street. They are meant for helping you. They are not meant for controlling you. But when you agree to be controlled by the police, then it will control you. Prakṛteḥ kriyamāṇāni guṇaiḥ karmāṇi sarvaśaḥ (BG 3.27). Then you become under the police control, if you become criminal. And what is that criminality? The criminality is that kṛṣṇa bhuliya jīva bhoga vāñchā (Prema-vivarta). Kṛṣṇa is the original enjoyer, God. When I speak "Kṛṣṇa," it means God. God has got many names according to different religious system. But the real name is Kristo. And you will be glad to understand that this Kristo, it is a Greek word, and it is a perverted pronunciation of Kṛṣṇa, this Greek word. The meaning of Kristo in Sanskrit dictionary and the Greek dictionary always the same, about this word. And from this Kristo the word has got Christo, or Christ. So even in Christian world the God's name is there—Jesus the Christ, or Jesus the son of Kristo, or Kṛṣṇa.
