大般涅槃經疏 18.20

18.20

「云何念施」下，第五念，謂修善因。言雜華者，《觀佛三昧海經》云「我於雜華已為普賢、賢首等說。」此土無《雜華經》唯有《華嚴》，或謂別有《雜華》，不來此土。一云：《觀佛三昧》云「雜華者是華嚴。」

From "What is mindfulness of giving?" onwards is the fifth recollection, which refers to cultivating the wholesome cause. As for the expression "mixed flowers" (Záhuā), the *Sūtra on the Ocean of Samādhi of Visualizing the Buddha* states: "In the *Záhuā* I have already preached it for Samantabhadra, Bhadraśrī, and others." In this land there is no *Záhuā Sūtra*, only the *Avataṃsaka*, so some say there is a separate *Záhuā* that has not come to this land. Another says: the *Sūtra on the Samādhi of Visualizing the Buddha* says that "*Záhuā* is the *Avataṃsaka*."
