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

Yesterday concluded with:

The Buddhas expound the Dharma
In perfect freedom.
Knowing the various desires and dispositions
Of all living beings,
They expound the Dharma
With innumerable parables
And with innumerable similes
According to their capacities.

And in the Simile of the Herbs, Sakyamuni clarifies that there is only one Dharma:

Kasyapa, know this! I, the Tathagata, am like the cloud. I appeared in this world just as the large cloud rose. I expounded the Dharma to gods, men and asuras of the world with a loud voice just as the large cloud covered all the one thousand million Sumeru-worlds. I said to the great multitude, ‘I am the Tathagata, the Deserver of Offerings, the Perfectly Enlightened One, the Man of Wisdom and Practice, the Well-Gone, the Knower of the World, the Unsurpassed Man, the Controller of Men, the Teacher of Gods and Men, the Buddha, the World-Honored One. I will cause all living beings to cross [the ocean of birth and death] if they have not yet done so. I will cause them to emancipate themselves [from suffering] if they have not yet done so. I will cause them to have peace of mind if they have not yet done so. I will cause them to attain Nirvana if they have not yet done so. I know their present lives as they are, and also their future lives as they will be. I know all. I see all. I know the Way. I have opened the Way. I will expound the Way. Gods, men and asuras! Come and hear the Dharma!’

And while the Buddha “expounded to them an innumerable variety of teachings according to their capacities in order to cause them to rejoice and receive benefits with pleasure” it was all one content:

The various teachings I expound are of the same content, of the same taste. Those who emancipate themselves [from the bonds of existence,] from illusions, and from birth and death, will finally obtain the knowledge of the equality and differences of all things. But those who hear or keep my teachings or read or recite the sutras in which my teachings are expounded, or act according to my teachings, do not know the merits that they will be able to obtain by these practices. Why is that? It is because only I know their capacities, appearances, entities and natures. Only I know what teachings they have in memory, what teachings they have in mind, what teachings they practice, how they memorize the teachings, how they think of the teachings, how they practice the teachings, for what purpose they memorize the teachings, for what purpose they think of the teachings, for what purpose they practice the teachings, and for what purpose they keep what teachings. Only I see clearly and without hindrance that they are at various stages [of enlightenment]. I know this, but they do not know just as the trees and grasses including herbs in the thickets and forests do not know whether they are superior or middle or inferior. My teachings are of the same content, of the same taste. Those who emancipate themselves [from the bonds of existence,] from illusions, and from birth and death, will finally attain Nirvana, that is, eternal tranquility or extinction. They will be able to return to the state of the Void.
