Gather pictures of people, places, and things for which you feel compassion. You may take photos yourself, cut them out of magazines and newspapers, copy them from books, or find them in the direct mail appeals from service organizations. Look for strong pictures to which you have an emotional response, no matter how painful. Include examples of the suffering of animals, nature, and things. Add words or symbols to represent others areas of concern -- "Earthquake" to remind you to feel compassion for victims of natural disasters, "Incest" to recall those suffering from sexual abuse, "Prison" for political prisoners and those who have committed crimes, "Garbage" to note the suffering caused by wasteful consumption. Leave one area of your collage blank for what has not yet touched your compassionate heart. Keep your collage in a place where you can contemplate it at least once every day. One or more images may become the focus of prayer or a catalyst for meditation.
