The four sages were the first-born sons of Brahmā. Therefore all other living entities, including Lord Śiva, are born later and are therefore younger than the four Kumāras. Although they looked like five-year-old boys and traveled naked, the Kumāras were older than all other living creatures and had realized the truth of the self. Such saints were not to be forbidden to enter the kingdom of Vaikuṇṭha, but by chance the doormen objected to their entrance. This was not fitting. The Lord is always anxious to serve sages like the Kumāras, but in spite of knowing this fact, the doormen, astonishingly and outrageously, prohibited them from entering.
