He who is the strongest will reign.. the people, unable to bear the heavy burden, Kara-bhara (the load of taxes) will take refuge among the valleys. . .

He will re-establish righteousness on Earth, and the minds of those who live at the end of Kali-Yuga shall be awakened and become as pellucid as crystal. The men who are thus changed. . . shall be the seeds of human beings, and shall give birth to a race who shall follow the laws of the Krita age, (the age of purity). As it is said, 'When the sun and moon and the lunar asterism Tishya and the planet Jupiter are in one mansion the Krita (or Satya) age shall return.'
