SB 9.10.53
TRANSLATION
When Lord Ramacandra, the Supreme Personality of Godhead, was the King of this world, all bodily and mental suffering, disease, old age, bereavement, lamentation, distress, fear and fatigue were completely absent. There was even no death for those who did not want it.
PURPORT
All these facilities existed because of Lord Ramacandra’s presence as the King of the entire world. A similar situation could be introduced immediately, even in this age called Kali, the worst of all ages. It is said, kali-kale nama-rupe krsna-avatara: Krsna descends in this Kali-yuga in the form of His holy name — Hare Krsna, Hare Rama. If we chant offenselessly, Rama and Krsna are still present in this age. The kingdom of Rama was immensely popular and beneficial, and the spreading of this Hare Krsna movement can immediately introduce a similar situation, even in this Kali-yuga.
