One day the sage Narada and Krishna were passing by the river Ganges and were discussing man’s place on earth. The sage said, “Lord, the only thing that I cannot understand is, how and why so easily does this poor creature, man, fall into the snares of illusion. If he could only keep his mind, on one subject and not let it drift, (have one subject only in mind) there is no chance for him to go astray and take so many ages to be enlightened.” Krishna said, “Yes, Narada, if their minds were as steady as yours then perhaps they would be able to avoid the snares of illusion. But let poor man go his way for, as I see the Ganges below, I would like to have a cup of water from this cool and refreshing river. Can you oblige me?”The story goes on to say that sage Narada came down to the banks of the river with the purpose of fetching some water when he saw a young girl. She started discussion on the subjects of life, death, immortality and the Divine Being. The sage was anxious to know who this young girl was. He spent a long time discussing with her, the cup with the Ganges water in his hand. He completely lost sight of the fact that Krishna was waiting for him, and of his purpose in coming down to the river. The young girl then once again took the form of Krishna and said, “You see Narada, even after seeing and knowing the Divine Being, it is possible to forget. Even a mind steady as yours, drifts from the contemplation of the main subject – then how much more difficult it should be for mortals who, though they know not, will forget their purpose as you do, drift away and completely forget their goal.”
