大般涅槃經義記 4.49

4.49

In the second section, 'although this milk emerges from grass and blood, it cannot be called two' properly explains non-duality. That grass and blood produce milk is their difference; to distinguish the difference while including the oneness, it therefore says 'although'. The preceding is transformed into the succeeding, and therefore it cannot be categorically fixed as two. From 'it can only' downward, it explains and completes the non-duality: it is only from the conditions of grass and blood that milk is produced, and not from anywhere else; therefore it cannot be categorically fixed as two. From 'cheese up to' downward, it infers the subsequent by the initial; from 'for this reason' downward, it concludes the non-duality. Because these such as milk are produced subsequent from prior, and their nature is without distinction, they are jointly named bovine flavour; because the bovine flavour is identical, it is called non-dual.
