When a pagan came to Hillel and demanded to be taught the entire Torah on one foot, Hillel did not kick him out but said simply, "What you do not want others to do to you, do not do to others. The rest is commentary." Hillel was not being cute, flippant, or evasive, but stating a profound truth that reflects the essence of the Divine. According to religion scholar Karen Armstrong, whose books include The History of God, The Spiral Staircase, and twenty other must-reads on religion, history and society, all religions of the world have at their core this truth: that to reach God, one must live a compassionate life -- proactively, passionately, and profoundly. Compassion is not weakness, nor is it passive or ambivalent. Compassion is powerful, activist, and potentially worldchanging. Here in this inspiring and provocative video, this former nun who once swore off religion argues that religion can bring world peace. She articulates more than any rabbi I have ever heard the most profound spiritual truths of the universe. Karen Armstrong: Charter for Compassion
