Description of the Kali Yuga in The secret doctrine.

As the “Satya-yuga” is always the first in the series of the four ages or Yugas, so the Kali ever comes the last. The Kali yuga reigns now supreme in India, and it seems to coincide with that of the Western age.
 
Anyhow, it is curious to see how prophetic in almost all things was the writer of Vishnu Purana when foretelling to Maitreya some of the dark influences and sins of this Kali Yug. For after saying that the “barbarians” will be masters of the banks of the Indus, of Chandrabhaga and Kasmera, he adds:
 
“There will be contemporary monarchs, reigning over the earth - kings of churlish spirit, violent temper, and ever addicted to falsehood and wickedness. They will inflict death on women, children, and cows; they will seize upon the property of their subjects, and be intent upon the wives of others; they will be of unlimited power, their lives will be short, their desires insatiable ……  People of various countries intermingling with them, will follow their example; and the barbarians being powerful (in India) in the patronage of the princes, while purer tribes are neglected, the people will perish (or, as the Commentator has it,  ‘The Mlechchas will be in the  centre  and the Aryas in the end.’)[1] Wealth and piety will decrease until the world will be wholly depraved. Property alone will confer rank; wealth will be the only source of devotion; passion will be the sole bond of union between the sexes; falsehood will be the only means of success in litigation; and women will be objects merely of sensual gratification. …… External types will be the only distinction of the several orders of life; …… a man if rich will be reputed pure; dishonesty (anyaya) will be the universal means of subsistence, weakness the cause of dependence, menace and presumption will be substituted for learning; liberality will be devotion; mutual assent, marriage; fine clothes, dignity. He who is the strongest will reign; the people, unable to bear the heavy burthen, Khara bhara (the load of taxes) will take refuge among the valleys. …… Thus, in the Kali age will decay constantly proceed, until the human race approaches its annihilation (pralaya) …… When the close of the Kali age shall be nigh, a portion of that divine being which exists, of its own spiritual nature …… shall descend on Earth …… (Kalki Avatar) endowed with the eight superhuman faculties…… 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’.”
