Day 20 completes Chapter 15, The Appearance of Bodhisattvas from Underground, and concludes the Fifth Volume of the Sutra of the Lotus Flower of the Wonderful Dharma.

Last month Sakyamuni identified the Bodhisattvas who rose up from the sky beneath the Saha World, but now we must deal with the doubts caused by Sakyamuni’s explanation.

Thereupon Maitreya Bodhisattva-mahasattva and the innumerable Bodhisattvas in the congregation doubted the Buddha’s words which they had never heard before. They thought:

How did the World-Honored One teach these great, innumerable, asamkhya Bodhisattvas, and qualify them to attain Anuttara-samyak-sarpbodhi in such a short time?

[Maitreya Bodhisattva] said to the Buddha:

World-Honored One! When you, the Tathagata, were a crown prince, you left the palace of the Sakyas, sat at the place of enlightenment not far from the City of Gaya, and attained Anuttara­samyak-sambodhi. lt is only forty and odd years since then.

World-Honored One! How did you do these great deeds of the Buddha in such a short time? Did you teach these great, innumerable Bodhisattvas, and qualify them to attain Anuttara­samyak-sambodhi by your powers or by your merits?
World-Honored One! No one can count the number of these great Bodhisattvas even if he goes on counting them for thousands of billions of kalpas. They have already planted roots of good, practiced the way, and performed brahma practices under innumerable Buddhas from the remotest past.

World-Honored One! It is difficult for anyone in the world to believe this. It is as difficult as to believe a handsome, black-haired man twenty-five years old who points to men a hundred years old and says, ‘They are my sons,’ or as to believe men a hundred years old who point to a young man and say, ‘This is our father. He brought us up.’ You are like the young man. It is not long since you attained enlightenment. But it is many thousands of billions of kalpas since the great multitude of these Bodhisattvas began to practice the Way strenuously in order to attain the enlightenment of the Buddha. During that time they entered into, stayed in, and came out of many hundreds of thousands of billions of samadhis, and obtained great supernatural powers. They performed brahma practices for a long time. They learned good teachings one by one, and obtained the ability to answer questions skillfully. They are regarded as the treasures of the world of men by alJ the people of the world because they are rare. Today you say that, after you attained the enlightenment of the Buddha, you caused them to aspire for enlightenment, taught them, and led them into the Way to Anuttara-samyak-sarnbodhi.

World-Honored One! You did these deeds of great merit although it is not long since you attained Buddhahood. We believe that your words given according to the capacities of all living beings are infallible, and that we understand all that you know. But the beginners in Bodhisattvahood after your extinction, if they hear these words of yours, will not receive them by faith but commit the sin of violating the Dharma. Therefore, World-Honored One! Explain all this so that we may be able to remove our doubts and that the go d men in the future may have no doubts when they hear these words of yours!

The Daily Dharma from June 26, 2016, underscores the importance of questioning:
