Compassion is like butter.  It greases bumpy spaces to ease frictions, and flavors many small pieces to make a stew.

Training in compassion therefore makes your thought processes more inclusive, less biased, and more creative.

This study on why we love to hate indicts us all, and at the same time gives us cause to laugh at ourselves, and be a big crazy group.

Humans are passionate creatures. Our passions drive us, gives us a sense of belonging, and unite us as few other things can. Still, there are only a couple of passions that have been constants down the ages, passions that people from every place and culture can agree on. Love is one, but another is that “those no-good bastards over there are trouble.” Of course, we quibble endlessly over the exact definition of “those” — every culture, pretty much, has had a different group in mind. But the singular fact of prejudice per se was as recognizable in Ancient Greece, Rome, and Samaria as it is now in modern Greece, Rome, and Arkansas.

Beware hate.  It is a sign of projection and self loathing at worst, or of a lack of imagination at best.
