金剛三昧經論 1.33

1.33

論曰：此第二句令他得入。言方便者，八相方便，謂從兜率天退乃至入涅槃故。神通者，六神通，即為三輪化眾生故。皆無相利者，如是八六方便神通，皆從自入實相而起，能令他得無相利故，標無相觀竟在於前。

The treatise says: This second phrase concerns causing others to attain entry. "Expedient means" refers to the expedient means of the eight phases [of a buddha's life], that is, from descending from Tuṣita Heaven up to entering nirvāṇa. "Supernatural faculties" refers to the six supernatural faculties, which constitute the three wheels for transforming sentient beings. "Are all the benefit of the signless" means that these eight [phases] and six [supernatural faculties], as expedient means and supernatural faculties, all arise from his own entry into the real character, because they are able to cause others to obtain the benefit of the signless. The brief marking of the contemplation of the signless has been completed above.
