The reason why a man has thousands of troubles...

From the Yin Chih Wen, or The Tract of the Quiet Way:

Hsieh Wen-Ching says: "The reason why a man has thousands of troubles is because he clings to the idea of self: therefore, he schemes and contrives in ten thousand different ways. He alone wants to be rich, he alone wants to be honored, he alone wants to be easy, he alone wants to be happy, he alone wants to enjoy life, he alone wants to be blessed with longevity; and to others' poverty, misery, danger, or suffering, he is altogether indifferent. It is for this reason that the life-will of others is disregarded and Heaven's Reason neglected. Only be cured of the disease of egotism, and your heart will be broadened even to the vastness of infinite space, so that wealth, honor, happiness, comfort, health, longevity could all be enjoyed with others. And, then, the will to live will have its way, everything will have its natural longings satisfied, and Heaven's Reason will be displayed in an untold exuberance.
