Day 25 covers all of Chapter 20, Never-Despising Bodhisattva, and opens Chapter 21, The Supernatural Powers of the Tathāgatas.

Having last month learned Śākyamuni’s connection to those in the congregation, we repeat in gāthās.

Thereupon the World-Honored One, wishing to repeat what he had said, sang in gāthās:

There was once a Buddha,
Called Powerful-Voice-King.
His supernatural powers and wisdom
Were immeasurable.
Leading all living beings, he is honored
By gods, men and dragons with offerings.

Some time after the extinction of that Buddha,
His teachings had almost died out.
At that time there lived a Bodhisattva
Called Never-Despising.
The four kinds of devotees at that time
Were attached to views.

Never-Despising Bodhisattva
Went to them,
And said,
“I do not despise you
Because you will practice the Way
And become Buddhas.”

When they heard this,
They spoke ill of him and abused him.
But Never-Despising Bodhisattva
Endured all this.

Thus he expiated his sin.
When he was about to pass away,
He heard this sūtra,
And had his six sense-organs purified.
He prolonged his life
By his supernatural powers,
And expounded this sūtra
To many people.

Those who were attached to views
Were led into the Way
To the enlightenment of the Buddha
By this Bodhisattva.

Never-Despising [Bodhisattva] met
Innumerable Buddhas after the end of his life.
He expounded this sūtra,
And obtained innumerable merits,
He quickly attained the enlightenment of the Buddha
By these accumulated merits.

While I’ve exhausted the Introduction to the Lotus Sutra‘s comment on Never Despising Bodhisattva, I recently came across this in Nichiren’s letter Tenjū Kyōju Hōmon, Lightening the Karmic Retribution:

The Nirvana Sūtra preaches a doctrine called “lightening the karmic retribution.” It proclaims that when a retribution accumulated from the evil karma in one’s previous lives is too heavy to be atoned for in this life, one will have to endure the suffering in hell in the future. One may, however, bear hell’s suffering in the present life instead so that one’s suffering in hell in a future life disappears instantly and one will instead be able to receive the blessings of the realm of humanity and that of heavenly beings, as well as the blessings of the Three Vehicles and attain Buddhahood after death. It was not without reason that Never Despising Bodhisattva was spoken ill of, slandered, beaten with sticks and pieces of wood, or had rubble thrown at him. His persecution in this life seems to be the consequences of his slandering the True Dharma in his previous lives. Therefore it is stated in the sutra, “His sins have been atoned.” [Or in Murano’s translation, “Thus he expiated his sin.”] I believe it means that Never Despising Bodhisattva’s past sin ceased to exist through his persecution.
