Dwring the Cakyua manutntamna there was a king named Sayavrata who was a great devorce of the Supreme Personality of Godhead. Satyavrata performed austerities by subsisting only
on water.
One day while King Satyavrata was offering water on the bank of the River Kṛtamālā, a small fish appeared in the water in his palms. Satyavrata threw the fish into the water of the river, along with the water in his palm. In a plaintive voice the poor, small fish said to King Satyavrata, "My dear king, protector of the poor, why are you throwing Me into the river, where there are other aquatics who can kill Me?I am very much afraid of them." Unaware that the fish was the Supreme Personality of Godhead, King Satyavrata gladly decided to help Him. The merciful king thus placed the fish into a water jug and brought Him to his own residence.
But in one night the fish grew so much that He could not move His body comfortably in the water of the pot. He then spoke to the king as follows: "O My dear king, I do not like living in this waterpot. Therefore please find some better reservoir of water where I can live comfortably."
After taking the fish out of the waterpot, the king threw Him into a large well. But within a moment the fish grew to the length of five feet.
The fish then said, "My dear king, this reservoir of water is not fit for My happy residence. Please give Me a more extensive pool of water, for I have taken shelter of you."
King Satyavrata then took the fish from the well and threw Him into a lake, but the fish at once assumeda gigantic form exceeding the extent of the water. The fish then said, "Oking, I am a large aquatic, and this water is not at all suitable for Me. Now kindly find some way to save Me. It would be better to put Me into the water of a lake that will never diminish."
Thus requested, King Satyavrata took the fish to the largest reservoir of water; but when that also proved insufficient, the king at last threw the gigantic fish into the ocean. While being thrown into the ocean, the fish said to King Satyavrata, "Ohero, in this water there are very powerful and dangerous sharks that will eat Me. Therefore you should not throw Me into this reservoir of water."
After hearing these sweet words from the Supreme Personality of Godhead in the form of a fish, the bewildered king asked Him, "Who are You, Sir? You simply bewilder me. In one day You have expanded Yourself for hundreds of miles, covering the water of the river and the ocean. Before this, I have never seen or heard of such an aquatic animal. My Lord, You are certainly the inexhaustible Supreme Personality of Godhead, Nārāyaṇa, Śrī Hari. It is to show Your mercy to the living entities that You have now assumed the form of an aquatic. O my Lord, master of creation, maintenance, and annihilation, O best of enjoyers, Lord Viṣṇu, You are the leader and destination of surrendered devotees. Therefore, let me offer my respectful obeisances unto You."
