Supernatural
Srimad-Bhagavatam
SB Canto 1
SB 1.10.6, Purport:
At the time of Mahārāja Yudhiṣṭhira, there were no different nations, although there were different subordinate states. The whole world was united, and the supreme head, being a trained king like Yudhiṣṭhira, kept all the inhabitants free from anxiety, diseases and excessive heat and cold. They were not only economically well-to-do, but also physically fit and undisturbed by supernatural power, by enmity from other living beings and by disturbance of bodily and mental agonies. There is a proverb in Bengali that a bad king spoils the kingdom and a bad housewife spoils the family. This truth is applicable here also.
