Day 22 covers all of Chapter 17, The Variety of Merits.

Having last month considered the innumerable merits of a moment’s faith, we repeat in gāthās.

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

Suppose someone practiced
The five paramitas
For eighty billion nayuta kalpas
In order to attain the wisdom of the Buddha.

Throughout these kalpas he offered
Wonderful food and drink,
Excellent garments and bedding,
And monasteries made of candana
And adorned with gardens and forests
To the Buddhas,
To the cause-knowers, to the disciples,
And to the Bodhisattvas.

Throughout these kalpas he made
These various and wonderful offerings
In order to attain
The enlightenment of the Buddha.

He also observed the precepts,
Kept purity and faultlessness,
And sought the unsurpassed enlightenment
Extolled by the Buddhas.

He was patient, gentle,
And friendly with others.
Even when many evils troubled him,
His mind was not moved.

He endured all insults and disturbances
Inflicted upon him by arrogant people who thought
That they had already obtained the Dharma.

He was strenuous and resolute in mind.
He concentrated his mind,
And refrained from indolence
For many hundreds of millions of kalpas.

He Lived in a retired place
For innumerable kalpas.
He sat or walked to avoid drowsiness
And to concentrate his mind.

By doing so, he became able to practice
Many dhyāna-concentrations.
His mind was peaceful, not distracted
For eighty billion kalpas.

With these merits of concentration of his mind,
He sought unsurpassed enlightenment, saying:
“I will complete all these dhyāna-concentrations,
And obtain the knowledge of all things.”

He performed
The meritorious practices
As previously stated
For hundreds of thousands of billions of kalpas.

The good men or women who believe my longevity,
Of which I told you,
Even at a moment’s thought
Will be able to obtain more merits than he.

I’ve recently been reading a lot about T’ien-t’ai Chih-i and his Profound Meaning of the Lotus Sutra. Chih-i’s focus on rendering the mind and opening oneself to the innate Buddha nature mirrors the meritorious practices detailed above. Thankfully, Nichiren realized that chanting Namu Myōhō Renge Kyō provides even more merits.
