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

Having last month described the grownups among the plants, it’s time to conclude the chapter.

As previously stated, Kasyapa, I expound the Dharma
And lead human flowers
[To the fruits of Buddhahood]
Just as the large cloud waters all flowers
By a rain of the same taste
And causes them to bear their fruits.

Kasyapa, know this!
I reveal the enlightenment of the Buddha
With various stories of previous lives,
With various parables and similes,
That is, with various expedients.
All the other Buddhas do the same.

Now I will tell you[, Sravakas,]
The most important truth.
You, Sravakas,
Have not yet attained [true] extinction.
What you are now practicing is
The Way of Bodhisattvas.
Study and practice it continuously,
And you will become Buddhas.

The Lecture on the Lotus Sutra offers this conclusion on the Simile of Herbs:

Concerning the Simile of the Herbs, it should be pointed out that all the plants live in harmony with each other. They are grouped together, even as they each grew according to their unique nature. Some would grow near mountains, some near the river, some in between. Yet they all grew together. Over and over in the Lotus Sutra the Buddha either refers to groups of people, alludes to groups of people or addresses groups of people. Even when he addresses specific individuals he does so as representatives for people of similar capacities. We each are important to the greater whole that makes up the entire universe as well as our local Sangha. Every person brings a unique perspective and understanding to the practice of Buddhism. The entire Sangha grows stronger by the contributions of each person, just as society is made stronger when all people actively participate.

It takes the combined efforts of many people to ensure that our society reflects the ideas and beliefs of Buddhism, which in turn will help eliminate the suffering that is around us in the world today.
