The interval preceding the cataclysm that might destroy humanity is marked by disorders announcing its end. Just as in the case of the brave assures from the Puranas, Shiva can destroy only the societies that have gone astray from their purpose, who have broken the natural law.
According to the theory of the cycles that regulate the evolution of the universe, (niyati), we are approaching the end of Kali Yuga, the age of conflicts, wars, genocides, dirty businesses, aberrant social and philosophical systems, the malefic development of knowledge that gets into irresponsible hands.
Everything tends to become equal, and this equanimity in all the fields and areas is actually the prelude of death. At the end of Kali Yuga, this process is accelerated, and this very acceleration is one of the signs indicating the approaching catastrophe.
The ancient Shaivite writings (The Puranas) describe in detail the signs that characterize the last part of Kali Yuga.
Linga Purana says: “the people of Kali Yuga are stimulated by the lowest instincts. They chose false ideas and concepts over the authentic ones, they have no hesitation in persecuting the wise, the envy torments them, negligence, disease, hunger and fear will spread.
The water will be very rare. Certain areas of some countries will oppose to others. The sacred books will not be respected any longer. The people will have no morals, and they will have a tendency towards sectaries. In the Iron Age, the false and deceiving doctrines will spread more and more.
People will be scared because they no longer respect the rites and they no longer listen the words of the sages.
Many will perish. The number of prices and agricultures will gradually decrease. The working classes will want to accede to the royal power and to the knowledge, rest and beds of their neighbors. The great majority of the new leaders will be of working class origin and they will obstinately pursue the priests and those who gained the knowledge.
They will kill the unborn child and they will murder their heroes. The low class (sudra) will pretend they were Brahmins, and the priests are like workers.
The thieves will become kings, and the kings will be like thieves. The number of the women who are prostitutes will increase.
The stability and balance of the four classes of society and of the four ages of life will disappear. The land will be very fertile in some places, bare, and unproductive in others.
The ruling classes will confiscate all proprieties and will use it badly. They will cease to protect the people. Worthless people, who have obtained through doubtful means a certain degree of knowledge without the power to use it, will be called wise men.
People who are not born to be fighters will become kings. The scientists will serve mediocre people, full of vanity and hatred.
The priests will lower themselves, selling sacraments. There will be a lot of people moving around from country to country, and the number of men will decrease, while the number of women will increase.
The predators will become more and more violent. The number of cows will decrease. Well-intended people will quit in playing an active role.
Already prepared food will be sold. The sacred books will be sold at the corner of the street. The young girls will sell their virginity. The god of clouds will give the rains unevenly. The salesmen will do dirty business and they will be surrounded by pretentious philosophers.
There will be plenty of beggars and people without work. Everybody will use low and harsh words. Nobody can be trusted at this time. People will be jealous of each other and they will not be able to do any free, disinterested service to anyone.
The degradation of the virtues and the censorship of hypocrite puritans will mark the end of Kali Yuga. There will be no more kings. The wealth and crops will diminish. The cities and villages will be filled with groups of bandits. Water and fruits will be wanted. The people supposed to ensure the protection of the people will not protect them.
The rapes will be frequent. Many children will be born when the life-hope will not be over 16 years. The adventurers will appear as monks with their heads shaved wearing orange garments, and beads around their necks.
The wheat will be stolen. The thieves will rob other thieves. People will become inactive, lethargic, without purpose and motivation. Diseases and poisonous substances will torment all people. Consumed by fear, people will find refuge in subterranean places, named (kausika).
The cases of the people living for 100 years will be rare. Sacred writings will be altered, and the rites neglected. The vagabonds will be many. Unqualified individuals will pass for experts in morals and religion. Many will massacre women, children, and cows and then they will kill among themselves.” (Linga Purana, cap. 40)
