Day 31 covers Chapter 27, King Wonderful-Adornment as the Previous Life of a Bodhisattva.

This story of two sons who, at the invitation of their mother, seek to convince their father, a king, to hear the Buddha is always inspiring. And this time through I want to underline the effect of their efforts:

By displaying these various wonders, they purified the mind of their father, that is, of the king, and caused him to understand the Dharma by faith.

And…

Thereupon the two sons descended from the sky, came to their mother, joined their hands together, and said to her, ‘Our father, the king, has now understood the Dharma by faith. He is now able to aspire for Anuttara-samyak-sambodhi. We did the work of the Buddha for the sake of our father.

And…

The two sons led their father by these expedients and caused him to understand the teachings of the Buddha by faith and to wish [to act according to those teachings].

They did the work of the Buddha and caused the king, their father, to understand the Dharma by faith and to wish to act according to those teachings.
