The city of the body is actually an ocean of misery

As long as he [the living entity] is in the city of the body, he appears to be the master of it, but actually he is neither its proprietor nor controller of its actions and reactions. He is simply in the midst of the material ocean, struggling for existence. The waves of the ocean are tossing him, and he has no control over them. His best solution is to get out of the water by transcendental Kṛṣṇa consciousness. That alone will save him from all turmoil.
