Yuga are something peculiar to Hinduism. There is some description of it in Christianity. Instantly. The story of Noah. In Hinduism it is the story of Manu.
But otherwise similar. Construction of a ship. The world as we now will change. And like starts again.
This story in Hinduism means the end of Kali Yuga
The point is – every so often there is a decline in moral values to an extent degree. In Satyuga morality is abundant and people live in harmony. Plus they are God fearing and abiding
Two other Yuga are of intermediate status. Treta and dwapar
So in Kali Yuga everything is upside down
Evil rules We see that
Good people seem to suffer more
Those in the entrainment business make a lot of money ( sports, movie, casino etc) but those working to save lives struggle ( firemen, police, physicians , nurses)
People will go to talk with fake Guru by the millions but will not go and talk with someone who can truly help
Importance is given to Politicians but not to the true intellectual who change everything in life
Being devious is the game
Money is worshipped
Life is perceived as something to just enjoy ( But it is about finding God)
I am sure you can come up with a much longer list
So this is Kali Yuga ! Still want to stay here?
