So this is going on. This is called illusion. He has no connection with all these things. When one realizes that "I have no connection with this body, this country, this wife, these children, this soc... They're all illusory," that is called liberation. That is called brahma-bhūtaḥ prasannātmā [Bg. 18.54]. People are suffering, identifying himself with these false things, which is not. Ātmānaṁ tri-guṇātmakam. Tri-guṇa, these, all these materials, they are manufactured by the three modes of material nature, and he's, he has no connection with the material nature. But somehow or other, he is now fallen in the ocean of the... Just like you have no connection with ocean. Your place of living is land. But some way or other, if you are thrown in the Pacific Ocean, that is a very troublesome business. You have to swim always. You have to protect... But still, you are unsafe. It doesn't matter you are a very great swimmer, doesn't matter. When you are in the Pacific Ocean, you are in danger.
So similarly, when that very man is taken away from the Pacific Ocean and put into the land, then he becomes prasannātmā, "Oh, I am saved." Brahma-bhūtaḥ prasannātmā. "Now I am on the saved..." Brahma-bhūtaḥ prasannātmā na śocati na kāṅkṣati [Bg. 18.54], that when one is in full knowledge that "I have nothing to do with this material world, that everything made by the material nature, that is illusion, I have nothing to do with anything of them, I am spirit, ahaṁ brahmāsmi. I am spirit soul. Now I have my business with the spiritual world," that is liberation. That is liberation. And the means which help you to come to that position, that is called spiritual life, sanātana-dharma.
