成唯識論演祕 6.14

6.14

略有二釋，一云燈明及炷以喻同時心、心所法；二云如燃眾燈其明和合，諸心、心所和合亦爾。

There are briefly two interpretations: First, it says that the light of the lamp and the wick illustrate simultaneous citta and caitasikas; second, it says that just as when many lamps are lit their lights blend together, the blending together of the citta and caitasikas is also like this.
