Most of us are compassionate by nature and we do not mind helping out people within our radar, if it is within our capacity. Yet, when the individuals or the organization we extend help to come back to us time and again to seek further help, we become uncomfortable.
We start suspecting the recipient of our charity to be dubious or greedy by nature. Sooner or later most of us become wary or aggressive. It really takes a mighty large heart and a sound conviction to accommodate and assist somebody in need unquestioningly.
An instance from the Agni Purana enumerates one such experience of king Satyavrata who was offering his morning prayers on the banks of river Kritamala. When the king scooped up the water from the river, he found a tiny little fish wriggling in the little water in his palms. Satyavrata instantly wanted to return the fish to the river, but he was taken aback when the fish spoke to him and requested that the king protect him from the mighty river.
Satyavrata was filled with compassion for the tiny creature and dropped the fish into his Kamandalam (water jug). When he reached the palace, he was surprised to see that the fish had enlarged and he transferred it to a large golden bowl. A little while later, the fish seemed to have outgrown its station and at its request, the king got it transferred to the water tank in the palace. In no time the size of the fish matched that of the tank. The king was puzzled by the constant growth of the creature. He understood that it was no ordinary living being. Though Satyavrata did not quite understand the happenings with the fish, his sense of confidence prevented him from panicking. His consideration for the fish which sought his refuge did not diminish. At that point of time, Satyavrata did not quite realize that Lord Vishnu had manifested himself as a fish and sought his help to save the world. All the same he got his gigantic refugee transferred into a large river and then the sea. Perhaps this was the reason why lord Vishnu selected Satyavrata to help the world regenerate after the impending deluge which would annihilate the earth.
