Can you revise your perceptions to see the world in terms of suffering and the end of suffering, instead of good and bad? To see the world in terms o… - Sharon Salzberg

Seeing the goodness in someone does not imply ignoring their difficult qualities or unskillful actions. Rather, we can fully acknowledge these difficulties, while at the same time we choose to focus on the positive. If we focus on the negative, we will naturally feel anger, resentment or disappointment. If we focus on the positive, we will forge a connection to the person. Then as we look at their negative traits or actions, we do it as their friend. If two friends are looking at such difficult things, they do so standing side by side.
This mirroring quality, whereby we 'reteach a thing it's loveliness', is one of the greatest attributes of metta. The power of metta enables us to look at people and affirm the rightness of their wish to be happy; it affirms our oneness with them. The power of love reflects both to ourselves and others the manifold possibilities available in each moment.

The Buddha actually described at some length what he meant by being a good friend in the world. He talked about a good friend as someone who is constant in our times of happiness and also in our times of adversity or unhappiness. A friend will not forsake us when we are in trouble nor rejoice in our misfortune. The Buddha described a true friend as being a helper, someone who will protect us when we are unable to take care of ourselves, who will be a refuge to us when we are afraid.

We can understand the inherent radiance & purity of our minds by understanding metta. Like the mind, metta is not distorted by what it encounters.
