A person desiring liberation from material bondage must give up the association of persons interested in sex life and should not employ his senses externally [in seeing, hearing, talking, walking and so on]. One should always stay in a secluded place, completely fixing his mind at the lotus feet of the unlimited Personality of Godhead, and if one wants any association at all, he should associate with persons similarly engaged.
