Day 9 covers Chapter 5, The Simile of Herbs, and introduces Chapter 6, Assurance of Future Buddhahood.

The Simile of Herbs uses various kinds and sizes of plant life to show how those who receive the rain of the Dharma will reach various stages of enlightenment according to their capacities.

I always find the explanation of plants and corresponding living beings to be very interesting.

Those who live among gods and men,
Or those who live with a wheel-turning-holy-king,
Or with King Sakra or with King Brahman,
May be likened to the small herbs.

Those who know the Dharma-without-asravas,
Who attained Nirvana,
And who obtained the six supernatural powers,
Including the three major supernatural powers,
May be likened to the middle herbs.
So may those who live alone in mountains or forests,
Who practice dhyana-concentrations,
And who attained the enlightenment of cause-knowers.

Those who seek the stage of the World-Honored One,
Who practice endeavors and concentration of mind,
And who wish to become Buddhas,
May be likened to the large herbs.

My sons [, that is, the Bodhisattvas]
Who seek
The enlightenment of the Buddha exclusively,
Who believe that they will become Buddhas definitely,
And who have compassion towards others,
May be likened to the short trees.

The Bodhisattvas
Who turn the irrevocable wheel of the Dharma
By their supernatural powers,
And who save many thousands of myriads
Of millions of living beings,
May be likened to the tall trees.

And later on:

Both the Sravakas and the cause-knowers,
Who live in mountains or forests,
Who have reached the final stage
of their physical existence,
And who have attained enlightenment by hearing the Dharma,
May be likened to the herbs
Which have already grown up.

The Bodhisattvas
Who resolve to seek wisdom,
Who understand the triple world,
And who seek the most excellent vehicle,
May be likened to the short trees
Which have already grown up.

Those who practice dhyana,
Who have supernatural powers,
Who have great joy
When they hear that all things are insubstantial,
And who save all living beings
By emitting innumerable rays of light,
May be likened to the tall trees
Which have already grown up.

Imagine, those “who live among gods and men” are just small hebs compared to the wheel-turning Bodhisattvas.
