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

Day 9 Text with annotations

Having last month considered how the Buddha sees the world, we consider how types of plants relate to those who hear the Dharma.

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-āsravas,
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 dhyāna-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.

Although my teachings are of the same content to anyone
Just as the rain is of the same taste,
The hearers receive my teachings differently
According to their capacities
Just as the plants receive
Different amounts of the rain water.

The Introduction to the Lotus Sutra offers this:

Traditionally, the small herbs are interpreted as humans and deities, the middle-sized herbs as “hearers” and “private Buddhas,” and the large herbs, stems, and branches as Bodhisattvas. The latter can be divided into three levels of accomplishment. The vast compassion of Sakyamuni is distributed equally to all living beings in order to lead them all to the enlightenment of the Buddha.
