Mother Ganges is available to everyone for bathing. Therefore, not only will sinful persons bathe in the Ganges water, but in Hardwar and other holy places where the Ganges flows, saintly persons and devotees will also bathe in the waters of the Ganges. Devotees and saintly persons advanced in the renounced order can deliver even the Ganges. Tīrthī-kurvanti tīrthāni svāntaḥ-sthena gadābhṛtā (Bhāg. 1.13.10). Because saintly devotees always keep the Lord within the core of their hearts, they can perfectly cleanse the holy places of all sinful reactions. Therefore, people in general must always respectfully honor saintly persons. It is ordered that as soon as one sees a Vaiṣṇava, or even a sannyāsī, one should immediately offer respects to such a holy man. If one forgets to show respect in this way, one must observe a fast for that day. This is a Vedic injunction. One must be extremely careful to refrain from committing offenses at the lotus feet of a devotee or saintly person.
There are methods of prāyaścitta, or atonement, but they are inadequate to cleanse one of sinful reactions. One can be cleansed of sinful reactions only by devotional service, as stated in regard to the history of Ajāmila:
kecit kevalayā bhaktyā
aghaṁ dhunvanti kārtsnyena
nīhāram iva bhāskaraḥ
“Only a rare person who has adopted complete, unalloyed devotional service to Kṛṣṇa can uproot the weeds of sinful actions with no possibility that they will revive. He can do this simply by discharging devotional service, just as the sun can immediately dissipate fog by its rays.” (Bhāg. 6.1.15) If one is under the protection of a devotee and sincerely renders service unto him, by this process of bhakti-yoga one is certainly able to counteract all sinful reactions.
