SB 12.2.1: Śukadeva Gosvāmī said: Then, O King, religion, truthfulness, cleanliness, tolerance, mercy, duration of life, physical strength and memory will all diminish day by day because of the powerful influence of the age of Kali.
SB 12.2.2: In Kali-yuga, wealth alone will be considered the sign of a man's good birth, proper behavior and fine qualities. And law and justice will be applied only on the basis of one's power.
SB 12.2.3: Men and women will live together merely because of superficial attraction, and success in business will depend on deceit. Womanliness and manliness will be judged according to one's expertise in sex, and a man will be known as a brāhmaṇa just by his wearing a thread.
SB 12.2.4: A person's spiritual position will be ascertained merely according to external symbols, and on that same basis people will change from one spiritual order to the next. A person's propriety will be seriously questioned if he does not earn a good living. And one who is very clever at juggling words will be considered a learned scholar.
SB 12.2.5: A person will be judged unholy if he does not have money, and hypocrisy will be accepted as virtue. Marriage will be arranged simply by verbal agreement, and a person will think he is fit to appear in public if he has merely taken a bath.
SB 12.2.6: A sacred place will be taken to consist of no more than a reservoir of water located at a distance, and beauty will be thought to depend on one's hairstyle. Filling the belly will become the goal of life, and one who is audacious will be accepted as truthful. He who can maintain a family will be regarded as an expert man, and the principles of religion will be observed only for the sake of reputation.
SB 12.2.7:
As the earth thus becomes crowded with a corrupt population, whoever among any of the social classes shows himself to be the strongest will gain political power.
SB 12.2.8: Losing their wives and properties to such avaricious and merciless rulers, who will behave no better than ordinary thieves, the citizens will flee to the mountains and forests.
SB 12.2.9: Harassed by famine and excessive taxes, people will resort to eating leaves, roots, flesh, wild honey, fruits, flowers and seeds. Struck by drought, they will become completely ruined.
SB 12.2.10: The citizens will suffer greatly from cold, wind, heat, rain and snow. They will be further tormented by quarrels, hunger, thirst, disease and severe anxiety.
SB 12.2.11: The maximum duration of life for human beings in Kali-yuga will become fifty years.
SB 12.2.12-16: By the time the age of Kali ends, the bodies of all creatures will be greatly reduced in size, and the religious principles of followers of varṇāśrama will be ruined. The path of the Vedas will be completely forgotten in human society, and so-called religion will be mostly atheistic. The kings will mostly be thieves, the occupations of men will be stealing, lying and needless violence, and all the social classes will be reduced to the lowest level. Cows will be like goats, spiritual hermitages will be no different from mundane houses, and family ties will extend no further than the immediate bonds of marriage. Most plants and herbs will be tiny, and all trees will appear like dwarf śamī trees. Clouds will be full of lightning, homes will be devoid of piety, and all human beings will have become like asses. At that time, the Supreme Personality of Godhead will appear on the earth. Acting with the power of pure spiritual goodness, He will rescue eternal religion.

When there is a predominance of cheating, lying, sloth, sleepiness, violence, depression, lamentation, bewilderment, fear and poverty, that age is Kali, the age of the mode of ignorance.
SB 12.3.31: Because of the bad qualities of the age of Kali, human beings will become shortsighted, unfortunate, gluttonous, lustful and poverty-stricken. The women, becoming unchaste, will freely wander from one man to the next.
SB 12.3.32: Cities will be dominated by thieves, the Vedas will be contaminated by speculative interpretations of atheists, political leaders will virtually consume the citizens, and the so-called priests and intellectuals will be devotees of their bellies and genitals.
SB 12.3.33: The brahmacārīs will fail to execute their vows and become generally unclean, the householders will become beggars, the vānaprasthas will live in the villages, and the sannyāsīs will become greedy for wealth.
SB 12.3.34: Women will become much smaller in size, and they will eat too much, have more children than they can properly take care of, and lose all shyness. They will always speak harshly and will exhibit qualities of thievery, deceit and unrestrained audacity.
SB 12.3.35: Businessmen will engage in petty commerce and earn their money by cheating. Even when there is no emergency, people will consider any degraded occupation quite acceptable.
SB 12.3.36: Servants will abandon a master who has lost his wealth, even if that master is a saintly person of exemplary character. Masters will abandon an incapacitated servant, even if that servant has been in the family for generations. Cows will be abandoned or killed when they stop giving milk.
SB 12.3.37: In Kali-yuga men will be wretched and controlled by women. They will reject their fathers, brothers, other relatives and friends and will instead associate with the sisters and brothers of their wives. Thus their conception of friendship will be based exclusively on sexual ties.
SB 12.3.38: Uncultured men will accept charity on behalf of the Lord and will earn their livelihood by making a show of austerity and wearing a mendicant's dress. Those who know nothing about religion will mount a high seat and presume to speak on religious principles.
SB 12.3.39-40: In the age of Kali, people's minds will always be agitated. They will become emaciated by famine and taxation, my dear King, and will always be disturbed by fear of drought. They will lack adequate clothing, food and drink, will be unable to properly rest, have sex or bathe themselves, and will have no ornaments to decorate their bodies. In fact, thepeople of Kali-yuga will gradually come to appear like ghostly, haunted creatures.
SB 12.3.41: In Kali-yuga men will develop hatred for each other even over a few coins. Giving up all friendly relations, they will be ready to lose their own lives and kill even their own relatives.
SB 12.3.42: Men will no longer protect their elderly parents, their children or their respectable wives. Thoroughly degraded, they will care only to satisfy their own bellies and genitals.
SB 12.3.43: O King, in the age of Kali people's intelligence will be diverted by atheism, and they will almost never offer sacrifice to the Supreme Personality of Godhead, who is the supreme spiritual master of the universe. Although the great personalities who control the three worlds all bow down to the lotus feet of the Supreme Lord, the petty and miserable human beings of this age will not do so.
SB 12.3.44:
Terrified, about to die, a man collapses on his bed. Although his voice is faltering and he is hardly conscious of what he is saying, if he utters the holy name of the Supreme Lord he can be freed from the reaction of his fruitive work and achieve the supreme destination. But still people in the age of Kali will not worship the Supreme Lord.
