"Leo Tolstoy (1828–1910) grappled with the question of human selfishness, including his own, pondering the cause of people’s self-centeredness and estrangement from others. He later reached the conclusion: “They and I are one. Everyone alive now, or in the past or the future, are all one; they are all one with me. My life is dependent on theirs, and their lives dependent on mine.” This became his guiding philosophy. His view of human life has much in common with Buddhism, which teaches that we remain linked to those in our lives throughout the three existences of past, present, and future, and that self and other are inseparable. It is important, therefore, for us to encourage each other and lead lives of great meaning and value by allowing the unsurpassed jewel of Buddhahood to shine forth brightly within us.
"When we help others shine, our lives shine, too. Dialogue enables us to appreciate our connection with others. The path of dialogue is the path of joy for both ourselves and others; it is the path of happiness."
