Lovingkindness and the other brahma viharas show us the possibility of an appropriate response to the joys and sorrows of life. The practice of mudita for oneself leads to the beautiful state of gratitude.
In order for metta to flow unobstructed, we need to be able to forgive—ourselves for ways we don't measure up to our high standards or unskillful actions, others for past hurts and life for the disappointments we experience. This talk explores these different levels of forgiveness.
What supports lovingkindness is the sincere caring we give in each moment as we say a metta phrase. What obstructs metta are its near and far enemies; affection with attachment and aversion such as sadness, fear, anger, or judgement.
