摩訶止觀 7.191

7.191

對境者：約眼計我，言我能受；一塵有三，合十八受者。眼見色有五陰、三界、二入，例如上說。又《彌勒相骨經》云：「一念見色，有三百億五陰生滅；一一五陰即是眾生。」若爾者，眼對色時，何啻五陰、三界、二入？若如此觀眼色者，名為「減修」，非摩訶衍。

Regarding the confronting of objects: taking the eye to reckon a self, saying 'I can experience'; one dust-object has three [kinds of sensation], totaling eighteen sensations. When the eye sees visible form, there are the five aggregates, three realms, and two bases, following the analogy above. Furthermore, the Maitreya-paripṛcchā-sūtra says: 'In a single thought-moment of seeing form, there are three hundred billion arisings and cessations of the five aggregates; each and every five aggregates is a sentient being.' If so, when the eye confronts visible form, how could it be merely the five aggregates, three realms, and two bases? If one contemplates eye and form in this way, it is called 'deficient cultivation' and is not the Mahāyāna.
