Krishna, the Supreme Personality of Godhead, could have killed all demon beings through his various material energies, but He wanted to kill them himself so that they would be granted salvation. Krishna did not have to come within the material universe to put to death the demonic beings; by his will alone, hundreds and thousands of demonic beings could have been destroyed without Himself having to make the slightest effort. But in truth, He chooses to appear for his pure devotees, to play the role of child with Mother Yasoda and Nanda Maharaja, and to delight the inhabitants of Dvaraka. By destroying demonic beings and protecting his devotees, Krishna thus establishes the true principle of all spirituality, that is, love for God. By observing this principle, even the so-called unclean beings were purified of all material defilement and promoted to the spiritual realm, such as motionless beings, trees and plants, and moving animals, and especially cows. When Krishna was on the planet, He delivered all the trees, the monkeys, and the other plants and animals that had the opportunity to see and serve Him in Vrindavana and Dvaraka.

Krishna has a city built on the sea.

Krishna decided to build an extraordinary fort, in a place where no biped, man or demon, could penetrate. There would be kept the members of his family, out of danger, while He would freely fight the enemy. It seems that formerly Dvaraka was part of the kingdom of Mathura, because the fort was built by Krishna in the open sea. Ruins of this fort still exist today, in the bay of Dvaraka, India.

Krishna first built a wall of great thickness, opening two hundred forty-nine square kilometers, entirely erected in the water. The plans and construction of this marvelous building were the work of Visvakarma. No architect could have built such a fortress on the sea, but Vivakarma, the engineer of celestial beings, is capable of producing amazing masterpieces anywhere in the universe. If one thinks that enormous planets can float without space in space by the cosmic order from God, the Supreme Person, the construction of a fort on two hundred and forty-nine square kilometers of marine space loses its character of marvelous prowess.

This new city built on the sea, very well built, had avenues, streets and alleys. There were even country lanes and well-ordered gardens, where the wish trees abounded. They have nothing in common with the ordinary trees of the material universe; they are only found in the spiritual world. Everything is possible according to the supreme will of the Lord, Sri Krishna; for example, planting wish-trees in a marine fortress. Dvaraka was adorned with magnificent palaces and immense portals. Today we still find these portals in some great temples. They are very tall and worked with extreme talent. On the portals and palaces were placed water jars in gold. They are considered, in this place, as auspicious signs.

Almost all the palaces of Fort Dvaraka seemed to touch the sky. In the cellars of every dwelling were jars filled with gold, silver and cereals. And in each room were placed golden vessels, filled with water. The rooms were adorned with precious stones, and
