Most of us are vaguely familiar with this attitude, because we are able to feel that way when our friends or relatives experience good fortune, and when something is going well for them, we want it to continue. We are also familiar with the attitude of compassion in a general sense. When friends or relatives are experiencing difficulties, we genuinely wish for them to become free of these sufferings. We have these basic qualities, but our experience of loving-kindness and compassion is, shall we say, tainted. It is something like the toy we call a yo-yo: you play with it and make it spin, but there is always a string attached. Similarly, we can afford genuine sympathy, concern, and loving-kindness for these people because they are our relatives, our friends, because they somehow seem to fit within our territory. There is a string attached; the pull is back towards ourselves. Therefore, egocentric tendencies and fixations remain, so these experiences are contaminated and are not free from deception. Still, although we have not worked on developing these qualities, we have glimpses of them because they are inherent potentialities.
