Here are two nice verses describing the glories of bathing in the river Ganges, and association with the pure devotee. How fortunate is this devotee who is helping the pure devotee Srila Prabhupada into the river.
O Sūta, those great sages who have completely taken shelter of the lotus feet of the Lord can at once sanctify those who come in touch with them, whereas the waters of the Ganges can sanctify only after prolonged use. (SB 1.1.15)
Dear Lord, Your personal associates, devotees, wander all over the world to purify even the holy places of pilgrimage. Is not such activity pleasing to those who are actually afraid of material existence? (SB 4.30.37)
…Pure devotees of the Lord are more powerful than the waters of the sacred river Ganges. One can derive spiritual benefit out of prolonged use of the Ganges waters. But one can be sanctified at once by the mercy of a pure devotee of the Lord.
