Since ancient times, the essential points of [Chapter 17] have been considered to be the “four faiths” (shishin) and “five categories” (go-hon). This division was first made in China by Chih-i in order to make the chapter more easily understood. The concept of the four faiths to be followed during the Buddha’s lifetime came from the idea that the ideal way of faith while the Buddha lived was to be divided into the following four stages: (1) receiving but one thought of faith and discernment concerning the eternity of the Buddha’s life, (2) apprehending its meaning, (3) devotion to preaching the Lotus Sutra abroad to others, and (4) beholding and perfecting profound faith and discernment.

The five categories of faith to be pursued after the Buddha’s extinction are derived from the idea that the ideal way of faith in the age of degeneration is divided into the following five categories: (1) first rejoicing over the Lotus Sutra, (2) reading and reciting it, (3) preaching it to others, (4) concurrently practicing the six pāramitās, and (5) intensively practicing the six pāramitās.

The first of the four faiths is to receive but one thought of faith and discernment concerning the eternity of the Buddha’s life. This is the first stage of faith, but the merits obtained by this practice are beyond limit or measure.
