In developing compassion for people whom you don't know, we give a lot of different reflection systems in order to try to get a little bit closer to these people's experiences, so that when we try to have compassion for groups of people, it's not so overwhelming.
One of the reflection systems that we give is to think of people in various occupations, then to try to think of some of the difficulties that would be involved in that occupation, and try to put yourself in their place. Then, whenever you meet somebody with this type of occupation, you'll automatically feel closer to these people even though you don't know them. So, we have quite a few different reflection systems for people that we don't know, but it is a practice to get closer to that compassion for these people; we can't automatically get closer, we need to practice.
