Day 15 concludes Chapter 10, The Teacher of the Dharma, and opens Chapter 11, Beholding the Stūpa of Treasures.

Since I get to return to the Stupa of Treasures when I complete the first half of the Lotus Sutra tomorrow, I’ll focus today on what is always my favorite message to those who wish to spread the teaching of this sutra:

Medicine-King! How should the good men or women who live after my extinction expound this Sutra of the Lotus Flower of the Wonderful Dharma to the four kinds of devotees when they wish to? They should enter the room of the Tathagata, wear the robe of the Tathagata, sit on the seat of the Tathagata, and then expound this sutra to the four kinds of devotees. To enter the room of the Tathagata means to have great compassion towards all living beings. To wear the robe of the Tathagata means to be gentle and patient. To sit on the seat of the Tathagata means to see the voidness of all things. They should do these [three] things and then without indolence expound this Sutra of the Lotus Flower of the Wonderful Dharma to Bodhisattvas and the four kinds of devotees.

And in gathas:

If you wish to expound this sutra,
Enter the room of the Tathagata,
Wear the robe of the Tathagata,
Sit on the seat of the Tathagata,
[And after doing these three things,]
Expound it to people without fear!

To enter the room of the Tathagata means
to have great compassion.
To wear his robe means to be gentle and patient.
To sit on his seat means to see the voidness of all things.
Expound the Dharma only after you do these [three] things!
