Interviewer: Is guru and swami the same thing?
Prabhupāda: Swami means practically the same idea. Swami means the master of the senses. One who has not control over senses, he cannot become guru. The renounced order means he's strictly away from all kinds of sense gratification, especially sex life. Therefore, he's called swami. Swami means the master. One who has become the master of the senses, he can become the spiritual master of the society. That is the idea.
