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

Having last month considered the rain cloud of the Dharma, we consider how the Buddha is like the large cloud.

I am like the cloud.
I appeared in this world
Just as the large cloud covered
Everything on the earth.

Since I appeared in this world,
I have been expounding
The reality of all things
To all living beings.

(The Great Saint,
The World-Honored One,
Said to the multitude
Of gods and men:)

I am the Tathāgata,
The Most Honorable Biped.
I have appeared in this world
Just as the large cloud rose.

All living beings are dying of thirst.
I will water them.
I will save them from suffering.
I will give them the pleasure of peace,
The pleasure of the world,
And the pleasure of Nirvana.
