I am assuming present time which we are living as kali yuga and also it is the last of the four yugas.
These words were taken from here
It is said that everyone will become godless. Whatever devotees, bhaktas, and sages are left on the planet will be so unique in character and peculiar compared with the rest of society that they will be ridiculed and hunted down in the cities for sport like animals.Thus, they will flee the cities to live underground in caves or high up in the mountains, or simply disengage from the earthly plane of existence. In this way, they will disappear from the face of the earth. That is the time when the dark influence of the age of Kali-yuga will become so dominant that its full influence will manifest without hindrance.
I know we cant prevent the ultimate fall to dark ages but Is there any duties which a Hindu or a human being should follow in this yuga.
