Everything is under the control of the Supreme Personality of Godhead, the supreme controller, and everyone must work accordingly. Just as a bull is controlled by a rope tied to its nose, so all conditioned souls are forced to work under the spells of the modes of nature. A civilized man, therefore, works according to the institution of varṇa and āśrama. Even in materialistic life, however, no one is free to act. Everyone is compelled to accept a certain type of body offered by the Supreme Lord and thus be allotted different grades of happiness and distress. Therefore even if one artificially leaves home and goes to the forest, he again becomes attached to materialistic life. Family life is compared to a fortress for practicing sense control. When the senses are controlled, one may live either at home or in the forest; there is no difference.
