Prabhupāda: Yes, I am the spiritual master of this institution, and all the members of the society, they're supposed to be my disciples. They follow the rules and regulations which I ask them to follow, and they are initiated by me spiritually. So therefore the spiritual master is called guru. That is Sanskrit language.
Interviewer: Guru means teacher.
Prabhupāda: Guru means not exactly teacher. Guru, the word, means heavy. Heavy. H-e-a-v-y, heavy.
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.
Interviewer: The swami... Now did I understand you to say the swami has no sex life?
Prabhupāda: No, certainly not.
