Vinasas tasya vidyate. Na vinasa. Vinasa means annihilation. So he has no annihilation. What is annihilation? We have understood from Bhagavad-gita in the Second Chapter that soul is never annihilated. Indestructible. Now how it is said that vinasa? Vinasa means when we are in the whirlpool of this material transmigration of soul from one body to another and we do not know where we are going. Either we are going, I am going to become an elephant or I'm going to become an ant, I do not know. After leaving this body, I'm in the wilderness of different species of life. So I forget myself. I forget myself. That is called vinasa. Vinasa means that living entity is not annihilated but he does not know where I am.
