One Kalpa (Day or Night of Brahma) corresponds to 4,320,000,000 human years.
Indeed earthly time is marked in Yuga or Ages, which are:
|Krita (or Satya)-Yuga||4,800 years *|
|Treta-Yuga||3,600 years *|
|Dwapara-Yuga||2,400 years *|
|Kali-Yuga||1,200 years *|
|Total||12,000 years *|
Each Yuga's length decrease progressively in relation to moral and physical decadence in each age, Throughtout the Satya Yuga virtue prevails and evil is unknown; in the Treta Yuga virtue falls by a fourth; in the Dwapara Yuga virtue has diminished by half; in the Kali Yuga, the current age, but a fourth of virtue remains.
The four Yuga make one Mahayuga or Caturyuga.The Mahayuga's 12,000 years must be multiplied by 360, the days of the human year.
At the end of this Yuga, Lord Shiva shall destroy the whole universe - this is known as the night of Brahma.
Unlike the other eras where one had to inevitably bear the punishment for a wrong and bad thoughts, In my era, this shall cease to happen but one shall be bestowed with good fruits who thinks good."
The influence of Kali Yuga is in four places where he could stay, wine, where a prostitute stays, where there is animal slaughter and where gambling would be allowed. Those people who yearn for higher ideals should not even go near these five things.
In the Kali Yuga, by seeking the blessings of Lord Jagannath Puri, one shall attain salvation.
Humans taking birth in this era will usually be radiant, bad tempered, greedy and untruthful. The personality will be plagued by flaws such as jealousy, ego, anger, pleasure, instinct, desires and greed.There shall be only one pillar of religion in the Kali Yuga. Here the idol of Bhagwan Vishnu has assumed a black colour because of the inherent chaos and delusion. Vedic conduct, religion, Yagya and Karma all cease to exist.
All types of problems such as ailments, lethargy, anger, mental diseases and hunger, thirst tend to aggravate. Gradually even happiness and comforts of humans become decadent and morbid. In this era Brahmins do the work of a Shudra and the Shudras alike the Vaishyas amass wealth or alike Kshatriyas engage in allied activities and earn their livelihood.
In Kali Yuga, Brahmins shall renounce self-study, contemplation and shall eat every thing that is prohibited. They will no more be inclined towards penance and on the contrary Shudras shall take interest in recitation of Vedic chants.
In this way when hypocrisy reaches the zenith, it initiates the final annihilation. Many a king of the inferior category shall reign the earth who shall be sinners, unfaithful and wicked. Kings of places such as Andhra, Shaka, Pulunda, Yavan, Kamboj, Bahrhik and other wealthy Aamir shall become kings. No Brahmin in this age shall earn his daily bread and butter honestly.
Many a creatures, insects etc. shall take birth in Kali Yuga. All things that ought to have fragrance shall not be that fragrant, and food shall relatively become tasteless. Women shall be short and have many children. Women in this era shall be immoral and licentious by nature. Most people shall be traders of food while Brahmins shall sell the Vedas. Most of the women shall engage in prostitution. In the Kali Yuga, there will be very less milk in the udders of the cow. Seldom will there be fruits and flowers on trees. There will be excessive number of crows in comparison to other birds. Brahmins will engage in killing and shall take donation from kings inspite of lying. Brahmins as a whole shall be imposters and feign to be very pious and pure. They will harass the common people for alms etc.
Householders shall indulge in robbery because they will be unable to pay up their taxes. They shall disguise in the form of sages, ascetics and earn their livelihood. Even people who are celibates shall give up their purity and engage in intoxication and shall have illicit sex. People will engage in all those material activities that ushers physical energy only. All Ashrams shall be a haven of all imposters and they shall be totally dependent on food from others. During this time, seldom shall it rain and even the yield, production of grain will not be satisfactory. People will be aggressive by nature and consequently unholy and impure. The ones indulging in irreligious and blasphemous acts shall emerge powerful and prosperous. Those who are righteous shall be in penury.
Just by amassing a little amount of wealth one shall become proud and they despite having wealth shall have an eye on others wealth and property. In Kali Yuga, girls, 8-10 years old shall become pregnant while boys of the age of 10-12 years shall have children. On the sixteenth year itself the hair will turn white. Youth shall become alike old men and old men shall become energetic and youthful. Women will engage in sex with inferior men, servants and animals inspite of having a good husband.
Any lake or reservoir situated far away will be referred as a holy shrine. Growing hair will be an indication of beauty. People will take interest in religious actions so as to become prosperous and successful. He who subdues the others shall be self-proclaimed king. Subjects to protect their families shall seek refuge in caves and caverns and will lead a miserable life.
People will be plagued with all types of extreme climatic conditions. Average life expectancy of a human being in Kali Yuga will be approximately 20 to 30 years only.As the delusion will aggravate people will become weak and devoid of radiance, medicines and food will plummet and all the four stages (Varnashrams) will be represented by Grihastashram (householder’s duty). By the end of the Kali Yuga, The God shall reincarnate to protect religion and to destroy all evil. Lord Vishnu shall incarnate and shall give refuge to all that are good and righteous.
He shall be the saviour of one and all and he will possess weapon on the spur of the moment. He shall emancipate this world from all miseries and create happiness. He will put an end to the Kali Yuga and shall create a novel Satya Yuga embellished with truth and beauty. Bhagwan Kalki shall recoronate all the Brahmins as the rulers and will massacre all the outcastes and inferior (barbarians)
