And back to the start, Chapter 1, Introductory.

It is inspiring to consider the 80,000 Bodhisattvas in attendance at the start:

They never faltered in [seeking] Anuttara-samyak-saṃbodhi. They had already obtained dhāraṇīs, turned the irrevocable wheel of the Dharma with eloquence according to the wishes [of all living beings], made offerings to many hundreds of thousands of Buddhas, and planted the roots of virtue under those Buddhas, by whom they had always been praised. They had already trained themselves out of their compassion towards others, entered the Way to the wisdom of the Buddha, obtained great wisdom, and reached the Other Shore so that their fame had already extended over innumerable worlds. They had already saved many hundreds of thousands of living beings.

Imagine the awe among the congregation when the Buddha’s illumination of the “eighteen thousand worlds in the east”:

The congregation saw from this world the living beings of the six regions of those worlds. They also saw the present Buddhas of those worlds. They also heard the Dharma expounded by those Buddhas. They also saw the bhikṣus, bhikṣuṇīs, upāsakas and upāsikās of those worlds who had already attained [the various fruits of] enlightenment by their various practices. They also saw the Bodhisattva-mahāsattvas [of those worlds] who were practicing the Way of Bodhisattvas [in various ways] according to the variety of their karmas which they had done in their previous existence, and also according to the variety of their ways of understanding [the Dharma] by faith. They also saw the past Buddhas [of those worlds] who had already entered into Parinirvāṇa. They also saw the stūpas of the seven treasures which had been erected to enshrine the śariras of those Buddhas after their Parinirvāṇa.

Maitreya Bodhisattva explains:

The four kinds of devotees
Are joyful.
They are happier than ever
In body and mind.

And …

The multitude of this congregation and I
Can see the various wonderful things
Of those worlds
By the ray of light of the Buddha [of this world].

The supernatural powers of the Buddha
And his wisdom are rare.
He is illumining innumerable worlds
By emitting a pure ray of light.
We were astonished
At seeing [those worlds].

Mañjuśrī, Son of the Buddha!
Remove our doubts!
The four kinds of devotees
Are looking up with joy at you and me,
Wishing to know why this ray of light is emitted
By the World-Honored One.
