1. Atonement for Vaisnava-aparadha

    The conclusion is that if Krsna consciousness is covered by material sins, one can eliminate the sins simply by chanting the Hare Krsna mantra, but if one pollutes his Krsna consciousness by offending a brahmana or a Vaisnava, one cannot revive it until one properly atones for the sin by pleasing the offended Vaisnava or brahmana. This was the course that Durvasa Muni had to follow, for he surrendered unto Maharaja Ambarisa. A vaisnava-aparadha cannot be atoned for by any means other than by begging the pardon of the offended Vaisnava.
