The great demigods could only remain silent, not knowing how to counteract the benediction. Then Lord Siva reached the luminous realm of Vaikuntha, beyond all darkness, where the Supreme Lord Narayana is manifest. That realm is the destination of renunciants who have attained peace and given up all violence against other creatures. Going there, one never returns.
According to Srila Sridhara Svami, Lord Siva entered the planet of Svetadvipa, a special outpost of the spiritual world within the confines of the material universe. There, on a
beautiful white island surrounded by the celestial Ocean of Milk, Lord Visnu rests on the serpent bed of Ananta Sesa, making Himself available to the demigods when they need His help.
