The practice of Buddhism is an art. Monks and nuns are artists and the materials which they use as artists are the five aggregates of form, feeling, discrimination, mental formations, and consciousness. The art is to bring harmony and peace into your five aggregates so that you can offer happiness to others. Truth, beauty, and goodness are found in art.
Good monastics are beautiful, which means that they embody goodness and truthfulness.
They are successful in the practice due to their mindfulness. Mindfulness leads to insight, understanding, compassion, and love. We practice mindfulness to increase our concentration, which leads us to look deeply. Then love arises in a natural way, and you are able to understand, accept, and be compassionate. The best thing a monastic can do is offer his or her understanding and love.
