首楞嚴義疏注經 5.245

5.245

觀此嘗味之根，不自體生，不他物生，各猶無生，共豈能有？緣中不得，非緣亦無，了味之知竟從何有？一根既爾，諸根亦然，由是應念得超諸漏。

He contemplated that this faculty of tasting flavor arises neither from its own substance nor from another object. Since each is already unarisen, how could they exist in conjunction? It cannot be found within conditions, nor does it exist apart from conditions. Whence could the consciousness that discerns flavors ever arise? Since this is true for one faculty, it is also true for all faculties. From this, in responding to thought, he was able to transcend all outflows.
