'When one attends on a tutor (spiritual guide), then one believes. One who does not attend on a tutor, does not believe. Only he who attends, believes. This attention on a tutor, however, we must desire to understand.' 'Sir, I desire to understand it.'

In plain words: Faith grows when a person stays close to and serves a spiritual teacher. Without this, a person does not have faith. So we must learn how to follow a teacher. Narada says he wants to learn it.
