Srimad-Bhagavatam: Canto 11 - Chapter 1 - Verse 28


तेषु नित्यं महाभाग महाभागेषु मत्कथा: ।सम्भवन्ति हि ता नृणां जुषतां प्रपुनन्त्यघम् ॥ २८ ॥


teṣu nityaṁ mahā-bhāgamahā-bhāgeṣu mat-kathāḥsambhavanti hi tā nṝṇāṁjuṣatāṁ prapunanty agham


O greatly fortunate Uddhava, in the association of such saintly devotees there is constant discussion of Me, and those partaking in this chanting and hearing of My glories are certainly purified of all sins.


Even if one does not receive direct instructions from a pure devotee, simply by hearing him glorify the Supreme Personality of Godhead one can be purified of all sinful reactions caused by one’s involvement in illusion.
