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.

The wise have explained that one result is derived from the culture of knowledge, and that a different result is obtained from the culture of nescience.
~Sri Ishopanishad, Mantra Ten

For one who lives a hedonistic life, a life in which nescience is cultivated, the results are envy, anger, greed, impatience, disrespect for others, anxiety, depression, hatred, ever-increasing lust, forgetfulness, frustration, dissatisfaction, duplicity, fear of death, and so on.
