The way of heaven is impermanent, and flowers bloom for one era. The past is like eternal sand, and the future is infinite light. One dharma and one kalpa, and the vision is wonderful and free. At the end of the kalpa, Bodhi is revealed, and the five aggregates are empty. ... Everything will eventually come to an end, and one kalpa will return. One calamity. The book has not finished its meaning, but the spirit of Xianfeng is still there.
