首楞嚴義疏注經 5.86

5.86

於是如來綰疊華巾又成一結，重問阿難：「此名何等？」阿難、大眾又白佛言：「此亦名結。」如是倫次綰疊華巾總成六結，一一結成，皆取手中所成之結持問阿難：「此名何等？」阿難、大眾亦復如是次第詶佛：「此名為結。」

Ānanda and the great assembly addressed the Buddha again: "This too is called a knot." In this sequential manner he folded and tied the patterned cloth until there were six knots in total. As each knot was completed, he held up the knot formed in his hand and asked Ānanda: "What is this called?" Ānanda and the great assembly likewise answered the Buddha in turn: "This is called a knot."
