The Six Difficult things are: 1) Expound this Sutra, 2) Copy and keep this Sutra, 3) Read this Sutra, 4) To keep this Sutra and expound to even one person, 5) To hear and receive this Sutra, and 6) Keep this Sutra after the death of the Buddha. In other words it is extremely difficult to keep, read, recite, copy, and teach the Lotus Sutra in this age so far removed from the historical Buddha. These things are more difficult than “putting the great earth on the nail of a toe and go up to the Heaven of Brahman.”
