How does one rise up out of selfishness and into compassion for oneself and others?

The key realization is: "All these people are suffering just like me!"

It is the kindredness of suffering and realizing all mankind are your family.

From here idiot compassion starts but if one is wise and logical and compassionate

Right mindful Compassion is born!

And from right mindful compassion: Civilizations are born!

When the wisdom of experience meets the compassion of realizing "Hey all these people are suffering just like me!" leads to civilization of the best kind all over the world.

When you see mankind as your family rather than your enemy or your competition, civilization of the best kind is born around the world.
