章中復云：地前有相亦得為地上無相因，以學似無相觀隨順彼無相故，如小乘見道前世間有漏智為緣，生見道出世無漏智等。

The Chapter also states: That with signs prior to the bhūmis can also serve as the cause for the signless on the bhūmis, because one trains in the contemplation that resembles the signless and accords with that signless, just as prior to the path of seeing in the Hīnayāna, worldly contaminated wisdom serves as a condition to produce the transworldly taintless wisdom of the path of seeing, and so forth.
