Buddhism for Today, p140Receiving and keeping the sutra (juji), reading and reciting it (doku-ju), expounding it (gesetsu), and copying it (shosha) are called the five practices of teachers of the Law (goshu hosshi). These are most important practices for those who spread the Lotus Sutra. The description of these five practices of the teacher of the Law is the first of the seven essentials mentioned in the chapter “A Teacher of the Law.”
Of these five practices of the teacher, “receiving and keeping” (juji) is called “the intensive practice” (shōgyō), while the other four practices are called “the assisting practic.es” (jogyō). The reason we must set apart “receiving and keeping” as the intensive practice is that this is the most important and fundamental practice of the five; without it, the other four practices mean little. “Receiving” (ju) indicates believing deeply in the teachings of the Buddha, and “keeping” (ji) means to adhere firmly to that belief.
