Here's another parable told by Sri Ramakrishna to illustrate the negative role played by worldly desires in the path of spiritual progress:
"It is narrated in the Bhagavata that the Avadhuta had twenty-four gurus, one of whom was a kite. In a certain place the fishermen were catching fish. A kite swooped down and snatched a fish. At the sight of the fish, about a thousand crows chased the kite and made a great noise with their cawing. Whichever way the kite flew with the fish, the crows followed it. The kite flew to the south and the crows followed it there. The kite flew to the north and still the crows followed after it. The kite went east and west, but with the same result. As the kite began to fly about in confusion, lo, the fish dropped from its mouth. The crows at once let the kite alone and flew after the fish. Thus relieved of its worries, the kite sat on the branch of a tree and thought: 'That wretched fish was at the root of all my troubles. I have now got rid of it and therefore I am at peace.'
"The Avadhuta learnt this lesson from the kite, that as long as a man has the fish, that is, worldly desires, he must perform actions and consequently suffer from worry, anxiety, and restlessness. No sooner does he renounce these desires than his activities fall away and he enjoys peace of soul." Courtesy: RKM Nagpur
