Day 21 covers all of Chapter 16, The Duration of the Life of the Tathāgata.

Having last month considered the expedients of the Eternal Buddha, we come to his purpose.

“Good men! All the sutras that I expounded [hitherto] were for the purpose of saving all living beings. I told the stories of my previous lives [in some sutras,] and the stories of the previous lives of other Buddhas [in other sutras]. I showed my replicas [in some sutras,] and my transformations [in other sutras]. I described my deeds [in some sutras,] and the deeds of others [in other sutras]. All that I say is true, not false, because I see the triple world as it is. I see that the triple world is the world in which the living beings have neither birth nor death, that is to say, do not appear or disappear, that it is the world in which I do not appear or from which l do not disappear, that it is not real or unreal, and that it is not as it seems or as it does not seem. I do not see the triple world in the same way as [the living beings of] the triple world do. I see all this clearly and infallibly. The living beings are various in their natures, desires, deeds, thoughts and opinions. Therefore, I expounded the dharma with various stories of previous lives, with various parables, similes and discourses, in order to cause all living beings to plant the roots of good. l have never stopped doing what I should do. As I said before, it is very long since I became the Buddha. The duration of my life is innumerable, asamkya kalpas. I am always here. I shall never pass away.

The Daily Dharma from July 19,2016, offers this:

I do not see the triple world in the same way as [the living beings of] the triple world do. I see all this clearly and infallibly.

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.

Having last month pondered grey-haired sons and young fathers we come now to the question at hand and the conclusion of Chapter 15.

We do not doubt your words
Because we heard them direct from you.
Explain all this so that the living beings in the future
May be able to understand your words, Buddha!

Those who doubt this sutra
And do not believe it
Will fall into the evil regions.
Explain all this to us now!

How did you teach these innumerable Bodhisattvas
In such a short time,
And cause them to aspire for enlightenment
And not falter in seeking enlightenment?

In searching past posts on the subject of “doubt,” I was reminded of what Mañjuśrī promised Maitreya all the way back in Chapter 1:

The Buddha will remove
Any doubt of those who seek
The teaching of the Three Vehicles.
No question will be left unresolved.

And, so, we await tomorrow.

Day 19 concludes Chapter 14, Peaceful Practices, and begins Chapter 15, The Appearance of Bodhisattvas from Underground.

Having last month heard the offer of the Bodhisattva-mahasattvas, more than eight times the number of the sands of the River Ganges, who had come from the other worlds, we greet the arrival of Bodhisattvas from Underground.

Thereupon the Buddha said to those Bodhisattva-mahasattvas:

“No, good men! I do not want you to protect or keep this sutra because there are Bodhisattva-mahasattvas sixty thousand times as many as the sands of the River Ganges in this Saha-World. They are each accompanied by attendants also numbering sixty thousand times as many as the sands of the River Ganges. They will protect, keep, read, recite and expound this sutra after my extinction.”

When he had said this, the ground of the Saha-World, which was composed of one thousand million Sumeru-worlds, quaked and cracked, and many thousands of billions of Bodhisattva-mahasattvas sprang up from underground simultaneously. Their bodies were golden-colored, and adorned with the thirty-two marks and with innumerable rays of light. They had lived in the sky below this Saha-World. They came up here because they heard these words of Sakyamuni Buddha. Each of them was the leader of a great multitude. The Bodhisattvas included those who were each accompanied by attendants as many as sixty thousand times the number of the sands of the River Ganges. Needless to say, [they included those who were each accompanied by less attendants, for instance,] fifty thousand times, forty thousand times, thirty thousand times, twenty thousand times or ten thousand times the number of the sands of the River Ganges, or by attendants just as many of the sands of the River Ganges, or by attendants as many as a half, or a quarter of the number of the sands of the River Ganges, or by attendants as many as the sands of the River Ganges divided by a thousand billion nayuta, a billion, ten million, a million, ten thousand, a thousand, a hundred, ten, five, four, three or two attendants, or only by one attendant. [The Bodhisattvas] who preferred a solitary life came alone. The total number of the Bodhisattvas was innumerable, limitless, beyond calculation, inexplicable by any parable or simile.

The Daily Dharma from July 29, 2016, offers this:

No, good men! I do not want you to protect or keep this sūtra because there are Bodhisattva-mahāsattvas sixty thousand times as many as the sands of the River Ganges in this Sahā-World. They are each accompanied by attendants also numbering sixty thousand times as many as the sands of the River Ganges. They will protect, keep, read, recite and expound this sūtra after my extinction.

Day 18 concludes Chapter 13, Encouragement for Keeping this Sutra, and begins Chapter 14, Peaceful Practices.

Having last month completed the first set of things a Bodhisattva should do, we come to the second set of peaceful practices to perform.

“Second, Manjusri! A Bodhisattva-mahasattva who wishes to expound this sutra in the age of the decline of the teachings after my extinction should perform the following peaceful practices. When he expounds or reads this sutra, he should not point out the faults of other persons or sutras. He should not despise other teachers of the Dharma. He should not speak of the good points or bad points or the merits or demerits of others. He should not mention Sravakas by name when he blames them. Nor should he do so when he praises them. He should not have hostile feelings against them or dislike them. He should have this peace of mind so that he may not act against the wishes of the hearers. When he is asked questions, he should not answer by the teachings of the Lesser Vehicle, but expound the Dharma only by the teachings of the Great Vehicle so that the questioners may be able to obtain the knowledge of the equality and differences of all things.”

The Lecture on the Lotus Sutra offers this perspective:

The second peaceful practice concerns the things we say. The list is a reminder of how we should speak, avoiding such things as being overly critical of others and other sutras. It is a fine line between pointing out differences in belief and practice and drifting to arrogance and disdain. We might be tempted to adopt the harsh language of Nichiren without fully manifesting the heart of Nichiren. The words are cheap and easy to use, the compassion and caring is difficult to manifest. There is also a time and place for things and this age we live in calls for great wisdom in discerning which approach is the most beneficial to the listener first and foremost and not to our own egotistical needs at proving superiority. As the Buddha says, the teacher should not have hostile feelings, nor dislike them but should have peace of mind. We should always have the wish to attain enlightenment for ourselves and cause others to do the same.
