法華義疏 3.264

3.264

初從定起則以神力令其起去，便不得聞於略說作未來得度因緣，若聞於廣說則起誹謗現在無益，以佛明見三世，故有遣不遣也。又初歎佛二智，身子未請，無因緣故不得遣之。今待請後許說，宜須簡眾方始得遣也。

If he had made them rise and leave by supernatural power as soon as he arose from samādhi, they would not have heard the brief explanation to serve as a cause and condition for their future deliverance; yet if they heard the detailed explanation, they would give rise to slander, which would be of no benefit in the present. Because the Buddha clearly sees the three times, there is a reason for dismissing them or not dismissing them. Furthermore, when he initially praised the Buddha's two knowledges, Śāriputra had not yet requested [the teaching], so there was no occasion to dismiss them. Now, having consented to speak after the request, it was appropriate to select the assembly, and only then could he dismiss them.
