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

For me, the specifics of what World-Voice-Perceiver Bodhisattva offers to do for people in need are as problematic as the specifics of the Merits of the Teacher of the Dharma. Get out of jail free, guilty or not, or recognize by smell the gold, silver, and other treasures deposited underground. But that’s just me.

In this first time through, I’ll focus on the empowering aspect of World-Voice-Perceiver Bodhisattva:

Good man! If many hundreds of thousands of billions of living beings hear [the name of] World-Voice-Perceiver Bodhisattva and call his name with all their hearts when they are under various sufferings, World-Voice-Perceiver Bodhisattva will immediately perceive their voices, and cause them to emancipate themselves [from the sufferings].

And in gathas:

Listen! World-Voice-Perceiver practiced
According to the conditions of the places [of salvation].
His vow to save [people] is as deep a 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.
