Day 3 covers the first half of Chapter 2, Expedients.

Having last month learned the expediency of the teaching of the Three Vehicles, we consider the reaction of the Śrāvakas and the Arhats.

The great multitude at that time included Śrāvakas. [They also included] Ājñāta-Kauṇḍinya, and other Arhats, twelve hundred altogether, who had already eliminated āsravas. [They also included] the bhikṣus, bhikṣunīs, upāsakās, and upāsikās, [that is, the four kinds of devotees] who had already aspired for Śrāvakahood or Pratyekabuddhahood. All of them thought:

“Why does the World-Honored One extol so enthusiastically the power of the Buddhas to employ expedients? Why does he say that the Dharma attained by him is profound and difficult to understand, and that the true purpose of his teachings is too difficult for Śrāvakas and Pratyekabuddhas to know? He expounded to us the teaching of emancipation. We obtained this teaching and reached Nirvāṇa. We do not know why he says all this.”

Thereupon Śāriputra, seeing the doubts of the four kinds of devotees, and also because he, himself, did not understand [why the Buddha had said this], said to the Buddha:

“World-Honored One! Why do you extol so enthusiastically [what you call] the highest [Truth, and the power of the Buddhas to employ) expedients? [Why do you extol) the Dharma which [you say] is profound, wonderful, and difficult to understand? I have never heard you say all this before. The four kinds of devotees also have the same doubts. World-Honored One! Explain all this! Why do you extol so enthusiastically the Dharma which [you say] is profound, wonderful, and difficult to understand?”

Lotus Path: Practicing the Lotus Sutra Volume 1 offers this on the followers’ puzzlement:

Previous to teaching the Lotus Sutra the Buddha taught expedients to lead people to the ultimate teaching of the Lotus Sutra. In many ways it was as if he were leading the blind to the train station so they could then find the way to the true complete teachings contained in the Lotus Sutra. But we need to remember that the train station is not the destination, the expedients are not the sum of the Buddha’s teachings.
