So a person's entire lifestyle can be dovetailed with his deep purpose in life. Such a person is the controller of his body, not a slave of his senses. Most people are servants of their senses and minds—they are godas (go means “senses”; das means “servant”). A bhakti yogi, however, strives to be a goswami (swami means “master,” and so goswami means “master of the senses”). A goswami is not dragged around by his senses, but instead uses his senses for his own desired purposes. Although goswami is also a title, in fact the real meaning of goswami is controller of the senses, whether one is externally with the title goswami, brahmachari, householder, or whatever.

If a person engages in the process of bhakti yoga and yet continues to engage in activities that are detrimental to spiritual progress, his spiritual progress will be very slow. This does not mean that a person must be completely free of all bad habits before he can even begin the process of bhakti yoga. For example, in the Philippines, one teacher saved many young people who were addicted to heroin and other drugs by teaching them the process of bhakti yoga. It took some time before they could completely give up all drugs; but eventually they did.
