Day 29 covers all of Chapter 25, The Universal Gate of World-Voice-Perceiver Bodhisattva.

Having last month covered Endless-Intent Bodhisattva’s offering to World-Voice-Perceiver, we come to the gāthās.

[The Buddha said to Endless-Intent Bodhisattva,] “Endless-Intent! World-Voice-Perceiver Bodhisattva goes about the Sahā-World, employing these supernatural powers without hindrance.”

Thereupon Endless-lntent Bodhisattva asked the Buddha in gāthās:

World-Honored One with the wonderful marks
I ask you about this again.
Why is the son of the Buddha
Called World-Voice-Perceiver?

The Honorable One with the wonderful marks answered Endless-Intent in gāthās:

Listen! World-Voice-Perceiver practiced
According to the conditions of the places [of salvation].
His vow to save [people] is as deep as the sea.
You cannot fathom it even for kalpas.

On many hundreds of thousands of millions of Buddhas
He attended and made a great and pure vow.
I will tell you about his vow in brief.
If you hear his name, and see him,
And think of him constantly,
You will be able to eliminate all sufferings.

Ryusho Shonin‘s Lecture on the Lotus Sutra quote fits well here:

The real value I think we as modern practitioners can find in Chapter 25, the Universal Gate of World-Voice-Perceiver Bodhisattva, is as a model for our own behavior. Through our practice we naturally develop empathy and an ability to listen to and respond to the suffering of others. We each have our unique talents to lend to others but through our practice we can develop greater skill in using those talents in the most effective way to benefit and bring joy to those around us who are suffering.Lecture on the Lotus Sutra
