注大乘入楞伽經 3.254

3.254

This refers to bringing the provisional back to the real. That some sūtras do not speak of emptiness and non-arising is because sentient beings' aspirations are not uniform; hence the Tathāgata, in accord with the minds of sentient beings, makes various differing explanations, yet the reality lies in mental awakening, not in words and texts. For example, a herd of deer pressed by thirst sees a spring mirage and conceives the notion of water, racing toward it in confusion; yet that sun-mirage is truly not water.
