2.676

述曰：方便者，所以義、因義、安立施設義、善巧義，非離假智及言說外有別所以，便施設自相。說為假智詮之所依。假智及詮，依所詮變與彼自相相似之義，說為假故，以為疎緣，親不得自性，得自性時不作青等解，作青等解即非自性，故知自性非假所依，然緣自性色。及詮故，作青等解，故說自相為假所依。

The Commentary states: 'Expedient' means the reason, the cause, the establishment and designation, or skillfulness. It is not that apart from nominal intellect and speech there is another distinct reason by which one then designates the particular characteristic, stating it to be the support for nominal intellect and expression. Because nominal intellect and expression, relying upon what is expressed, transform into a meaning that resembles that particular characteristic and are spoken of as nominal, they are considered indirect conditions; they do not directly grasp the intrinsic nature. When attaining the intrinsic nature, one does not form conceptualizations such as 'blue'; when forming conceptualizations such as 'blue', it is not the intrinsic nature. Hence we know that the intrinsic nature is not the support for the nominal. However, because one conditions the intrinsic nature of matter and its expression, one forms conceptualizations such as 'blue'; therefore the particular characteristic is spoken of as the support for the nominal.
