I have shared the Eucharist with Father Daniel Berrigan, and our worship became, possible because of the sufferings we Vietnamese and Americans shared over many years. Some of the Buddhists present were shocked to hear I had participated in the Eucharist, and many Christians seemed truly horrified. To me, religious life is life. I do not see any reason to spend one's whole life tasting just one kind of fruit. We human beings can be nourished by the best values of many traditions.
People kill and are killed because they cling too tightly to their own beliefs and ideologies.
When we believe that ours is the only faith that contains the truth, violence and suffering will surely be the result. Avoid being narrow-minded and bound to present views. Learn and practice nonattachment from views in order to be open to receive others' viewpoints. To me, this is the most essential practice of peace.
