This is very well illustrated by the myth of Ramachandra. It is said in the Purana that once Sita, the consort of Ramachandra, was staying in the guardianship of Vashista Rishi with her sons. The younger son, Lahu, one day went to see the neighboring town. He saw Kalanki, a most beautiful horse, running about the city without a rider. When he enquired whose the horse was, people told him that this horse had been let loose so that whoever was able to catch it should be made the king of that kingdom. This tempted the youth, and he ran after the horse in order to catch it. He continued running a long time, and met with nothing but disappointments. Every time he came close to the horse, thinking now he would catch it, it slipped from his hand. When he reached the point of utter disappointment, he saw his brother coming in search of him, sent by his mother, and he told him that he would not come back till he had caught the horse.
