3.2

「哢引」者，哢家之引。正說如哢，三序如引。「降臨」者，《周禮》云「臨，謂尊適卑也。」「生起意」者，因序中用，蓋致請故，佛示能除毒害者，在於西方，由示方所故勸祈請，由祈請故聖降，由聖降故授楊枝，由受楊枝故為說呪。

"Nong introduction": the prelude of an actor. The principal exposition is like the play, and the three introductory sections are like the prelude. "Descending" (jianglin): the Rites of Zhou states: "Lin means the superior approaching the inferior." "The purpose of the sequence": because within the sequence of causes Candraprabha extended the invitation, the Buddha indicated that the one who can remove the poisonous afflictions is in the western direction; because he showed the direction and location, he urged them to pray and request; because of the prayer and request, the sage descended; because the sage descended, he bestowed the willow branch; because the willow branch was received, he expounded the dhāraṇī for them.
