King Ajātaśatru’s skin disease was caused by committing the five rebellious sins and the sin of slandering the True Dharma. When the Buddha entered the Moon Love Meditation emitting rays of a pure light that shone on the body of the king, the rash of Ajātaśatru disappeared instantly and his remaining life span of three weeks was extended by as long as forty years. Therefore, King Ajātaśatru gathered 1,000 arhats to write down the holy teachings of the Buddha expounded during His lifetime so that the Buddhist sūtras remained to be spread after the passing of the Buddha throughout the Age of the True Dharma, that of the Semblance Dharma, and the Latter Age of Degeneration.
Now, your skin disease was caused solely by the sin of slandering the True Dharma. What is more, the Lotus Sūtra which you embrace is superior to the Moon Love Meditation. How then can you not cure the light skin disease and live long? If you find in the end my words have no effect, you should shout, “The Buddha, the eyes of the whole world, is a big liar; the One Vehicle teaching of the Lotus Sūtra is meaningless and false; if you are concerned for your reputation, please Śākyamuni Buddha carry out Your vow to save living beings, and many wise and holy beings who vowed before the Buddha to protect the Lotus Sūtra, come to help me.” Writing cannot wholly express my words and words cannot fully express what is in my mind. I hope to tell you more in detail when I see you.
