大方廣佛華嚴經隨疏演義鈔 89.41

89.41

In the commentary on the thirty-ninth [syllable], 'yasa' (也娑, pronounced yí-gè and sū-gè). If correlated with the sūtra, the 'nature of decrepitude and old age' is precisely the sphere of the Buddha-Dharma. Conjoined with the rest of aging and death, it is the sphere observed vigorously by the bodhisattva. The Mahāprajñāpāramitopadeśa states: 'If one hears the syllable kṣa (磋), one immediately knows that the syllable kṣa is empty, and so too are all phenomena.' The explanation says: Because this is a universal characteristic, there is no distinct explanation, yet the nature of decrepitude and old age is indeed a distinct meaning.
