SB 11.26.28
tesu nityam maha-bhaga
maha-bhagesu mat-kathah
sambhavanti hi ta nrnam
jusatam prapunanty agham
Translation:
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.
Purport:
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.
