The Lotus Sūtra, fascicle 7 (chapter 23, “Previous Life of the Medicine King Bodhisattva”), reads: “Propagate this sūtra throughout this world (Jambudvīpa) in the last 500-year period, namely at the beginning of the Latter Age of Degeneration, lest it should become extinct.”
Coming across this passage, I once lamented saying: “It has already been more than 2,220 years since Śākyamuni Buddha passed away. For what sin of mine was I neither born during the Buddha’s lifetime, nor fortunate enough to see the Four Reliances, four ranks of bodhisattva teachers whom people relied on after the death of the Buddha, in the Age of the True Dharma, or such great masters as T’ien-t’ai and Dengyō in the Age of the Semblance Dharma?”
Thinking it over, however, I was elated and said to myself, “How lucky I am to have been born in the last 500-year period and encounter the true teaching of the Lotus Sūtra!”
