Piyavadana

“Three thousand years ago there were maybe ten or a hundred million people.

Now there are over seven billion.

So, among all these people, there are certainly different dispositions. 

We can see this even among children of the same parents. Even twins, their minds and emotions are different.

Therefore, among humanity, there are different dispositions, different ways of life, different ways of thinking. These differences are also conditioned by the environment, geography, and climate.”

His Holiness the Dalai Lama
