1.355

謂一遍多時，還攝所遍之多在我一內。若以鏡燈喻者，如四方四維布八鏡，又上下各安一鏡為十。於中安一燈，即十鏡互入。如一鏡遍九鏡時，即容九在一內也。

This means that when the one pervades the many, it subsumes the many that are pervaded back into my one. If using the analogy of mirrors and a lamp: it is like arranging eight mirrors in the four cardinal and four intermediate directions, and placing one mirror each above and below to make ten. When a single lamp is placed in their midst, the ten mirrors mutually enter one another. Just as when one mirror pervades the nine mirrors, it immediately contains the nine within the one.
