Compassion for Others
Compassion for others is a technique recommended by the Dali Lama as a tool for increasing one's sensitivity to spiritual matters. By keeping the welfare of another in mind, you move from a self-centered position ot a more loving one.
This is not the same as helping others since the others may never know of your concern for them. It is also not the same a prayer and mediation although it can be an element of them.
The Dali Lama recommends starting with people you already care for as an easy way to get started. After starting with people you care for, you can move to people you are neutral about and to people you dislike. This stretching is spiritual growth. It helps to see what you have in common with all people, even the ones you don't like.
