The conditioned soul sometimes personally appreciates the futility of sense enjoyment in the material world, and he sometimes considers material enjoyment to be full of miseries. However, due to his strong bodily conception, his memory is destroyed, and again and again he runs after material enjoyment, just as an animal runs after a mirage in the desert.
The conditioned soul is forced to act under the pressure of the modes of material nature. He has no independence. When he is under the direction of the supreme personality of godhead he is free.
