大方廣佛華嚴經隨疏演義鈔 20.21

20.21

疏「二不來不去」下，有三義釋：初唯約體、二依體起用、三攝用歸體。初中背捨是去，而云不去者，智照妄空無可捨故，照惑無本即智體故。「向證真理」，合是來義，如如來故。而云不來者，真不可得故。照體無自，即真理故。故經云「如來者，無所從來。」

Under the commentary's "Second, neither coming nor going", there are three meanings in the explanation: first, solely in terms of essence; second, activating function based on essence; third, subsuming function back into essence. In the first, turning away and abandoning would be going, yet it says 'not going' because cognition illuminates delusion as empty, leaving nothing to abandon, and illuminating affliction as baseless is itself the cognitive essence. 'Approaching and verifying the true principle' should be the meaning of coming, as in 'Tathāgata'. Yet it says 'not coming' because the real cannot be attained. The illuminated essence has no selfhood and is itself the true principle. Therefore the sūtra states: 'The Tathāgata comes from nowhere.'
