瑜伽師地論略纂 12.46

12.46

論云「復有四種法嗢柁南」者，此云說也，即世尊常誦說。此若嗢柁南，名攝散，即以略偈而攝長行。今言說，謂常誦說，此義似無問自說也。若此四種體性以法體出諦，有為、無為故了知。

The śāstra states: "Furthermore, there are four kinds of dharmoddāna"—this means 'saying', that is, what the World-Honoured One constantly recited and spoke. If this uddāna means 'subsuming the scattered', it subsumes the prose discourses by means of brief verses. Here it says 'saying', referring to constant recitation and speaking; this meaning seems to be an *udāna* (unsolicited discourse). As for the intrinsic nature of these four kinds, when extracting the truths by the substantial nature of phenomena, they are conditioned and unconditioned, and are known accordingly.
