"Moreover, the Lotus Sutra states that it is “good medicine for the ills of the people of Jambudvipa.” The people of this world of Jambudvipa are suffering from illness, but they have the medicine of the Lotus Sutra. Now in your case, the three requirements are already present, so how could you fail to recover? But if you have doubts, I am powerless to help you."
