At the end of the Iron Age, these two kings, having received instructions directly from the Supreme Person, Vasudeva, return to human society and restore the eternal religion of man, characterized by respect and enforcement of social and spiritual class divisions, just as it was before.
The cycle of the four ages; the Golden Age, Silver Age, Copper Age, and Iron Age continue perpetually among living things on earth, repeating the same general sequence of events.
All of these kings and all other human beings come to this earth and claim their rights, but in the end, they all have to forsake this world and face their destruction.
Even though a person's body may now have the designation “king”, its name will eventually be “worms”, “faeces” or “ashes”. What can a person who injures other living things for the sake of his body know for his own self-benefit, since his activities simply lead him to hell?
The era of discord, quarrels, hypocrisy, indifference, decadence and sin began 5,000 years ago, which sees abounding conflicts, ignorance, irreligion and vice, where virtue has practically disappeared, lasts 432,000 years. In this age, immorality increases to such an extent that in the end the Supreme Lord appears in person, in the form of Avatar Kalki, to overcome demonic beings, save his devotees, restore spirituality, and to inaugurate a new age, that of the golden age, the age of virtue, purity and truth. Then the cycle resumes.
When Lord Kalki brings forth the next golden age, the age of virtue or the age of purity and truth, and delivered the earth and all that remains of civilization from the effects of the dark age, He will return to his eternal home with all his entourage and his heavenly host.
After Lord Kalki returns to his eternal home, when the Kali Age survivors were enlightened and spiritually transformed, the era changes overnight. The minds of all people will become enlightened, and with inevitable force the golden age, the age of virtue, purity and truth sets in.
Living beings will then realize their true spiritual soul identity. Each of them will know in conscience to be a spiritual entity. They will acquire piety, devotion, tranquility and a clear conscience.
Then the perfect beings, the accomplished, enlightened and perfected devotees who had remained on an Edenic planet in the upper region of the galaxy until the end of the dark age, return to earth, and again act openly. They join the seven wise men who are also returning, and together, educate everyone about the spiritual life, the Vedic knowledge, [of the Vedas, the original holy scriptures], and the progressive organization of society, the restoration of the four. social and spiritual classes, for a peaceful and fulfilling existence.
Thus, human beings flourish and perform sacred rites, and the sages will remain in authority to continue the advancement of the new golden age, the age of virtue, purity and truth. All beings then now walk with Krishna, God, the Supreme Person, they take pleasure in abandoning themselves to Him and serving Him with love and devotion.
