By chanting the different names of Lord Vishnu a thousand times, one may be bestowed with the same benefits as by thrice chanting the holy name of Lord Rama. Any by chanting the holy name of Lord Krishna only once, one receives the same benefit.
(Krishna, Chapter 90)
Just as Arjuna is deriving benefit by being in the same chariot with Lord Sri Krishna, we can also benefit by associating with Krishna through the chanting of His holy names.
(Path of Perfection, Chapter 10)
