….people are becoming degraded, forgetting God. That is their degradation. So at the end of this Kali-yuga they will be so much degraded that it will be impossible for them to understand God. At the present moment, although it is Kali-yuga, there are some persons who are trying to understand God. At least, there is attempt. But, at the end of Kali-yuga, say, about 400,000's of years, then people… Because they're becoming animals, more and more. The more we become animals, we cannot understand God. So our modern civilization is to make the people animal. That is advancement of civilization. Ahara-nidra-bhaya-maithunam ca samanyam etat pasubhih naranam. The modern civilization is how we can eat very nicely, how we can sleep nicely, how we can have sexual intercourse nicely, how we can defend nicely. Only these four principles are being taught. They have no idea what is soul, what is God, what is the relationship with the soul. So this is, this type of civilization is increasing. So just imagine how much it will be increased after four hundred thousands of years. The Kali-yuga has begun only five thousand years. Within this five thousand years, we have so much degraded, illusioned by the maya as advancement of civilization. This is maya. So the
more days go, we shall be more illusioned. So there will be no capacity to understand about God. At that time, God will come to destroy all this population by cutting their throat. That is kalki-avatara.
