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

Having last month heard the Buddha calling us, we consider how various people correspond to various plants.

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.
