大方廣圓覺修多羅了義經略疏 2.785

2.785

此況道者燕居靜室、或隱深山，心絕經營，境無違順，習閑成性，暫得忘情，不覺自他，謂證無我。若違順所逼，宛有心生，心既未平，方知我在。故下云：「若復有人歎謗其法，即喜恨等。」

This is an analogy for a practitioner who dwells at leisure in a quiet room or hides deep in the mountains, his mind having ceased worldly affairs and his environment having neither adverse nor agreeable conditions. Becoming accustomed to leisure as his nature, he momentarily forgets worldly sentiments and is unaware of self and other, considering this to be the realization of no-self. If pressed by adverse or agreeable conditions, a mind appears as if from nowhere; since the mind is not yet tranquil, only then does he realize that the self exists. Hence, below it says: 'If someone praises or slanders his teaching, joy, anger, and the like will arise.'
