Srila Jiva Gosvami points out that Tvashta, Visvakarma, manifested the expertise of the Supreme Lord, and thus he was able to build such exquisite palaces. Srila Prabhupada writes, "The great kings and princes of the world used to visit these palaces just to worship [Lord Krishna]. The architectural plans were made personally by Visvakarma, the engineer of the demigods, and in the construction of the palaces he exhibited all of his talents and ingenuity."
