1.573

一云，同界同處而不得一處生，是和合不相離，眾多燈光照一室中者，據實一燈不得遍照，故不大明，第三燈生時方乃明也。

One states: Sharing the same realm and the same location, yet unable to arise in a single identical place, this is non-separation of combination. When the light of many lamps illuminates a single room, strictly speaking, a single lamp cannot illuminate it everywhere and therefore is not very bright; only when a third lamp arises does it become bright.
