瑜伽師地論略纂 12.111

12.111

結釋名中，「由發聞行正法光明、等持光明之所顯示」者，由發聞行正法光明者，謂求法時，聞慧照法光明；因聞生修故，言等持光明等。由內心淨者，謂此地證內修慧光明，故言內心行。無漏名淨，意名為內心，謂即定也。

In the concluding explanation of the name, regarding 'manifested by radiating the light of practicing the true Dharma through hearing, and the light of samādhi': 'radiating the light of practicing the true Dharma through hearing' means that when seeking the Dharma, the light of hearing-prajñā illuminates dharmas; because cultivation arises based on hearing, it says 'the light of samādhi', and so forth. 'Due to inner mental purity' means that this bhūmi realizes the light of inner cultivated prajñā; hence it says 'inner mental practice'. Freedom from outflows is called 'purity', and the mind is called 'inner mind', which refers precisely to samādhi.
