Buddhism for Today, p116-117“The buddha preached this sutra incessantly for eight thousand kalpas. When he had finished preaching it, he entered a quiet room and remained in meditation for eighty-four thousand kalpas. Thereupon the sixteen bodhisattva-śramaṇeras, knowing that the buddha was absorbed in meditation, were concerned about what would happen if they did not preach the Law on behalf of the buddha. Each of them ascended a Law throne and according to the capacity of his listeners extensively preached and expounded to them the Sutra of the Lotus Flower of the Wonderful Law. Each of them showed, taught, benefited, and gladdened them, leading them to develop the mind leading to Perfect Enlightenment.”
A brief explanation should be given here of the words “Each of them showed, taught, benefited, and gladdened them.”
These words indicate the order of preaching the Law. First, one must show the general meaning of the teaching to people. Then, when one knows that they have generated the desire to enter the teaching, one must teach its profound meaning. Next, seeing that they appear to understand it, one must lead them to practice it and to obtain the benefit of the teaching. Lastly, one must so act toward them as to gladden them in keeping the teaching.
