首楞嚴義疏注經 10.229

10.229

根身虛妄，本是無常，實不可貪以為長久。今堅貪著，妄執長生，故云貪非貪執。阿斯陀者云無比，即長壽仙也。長勞果者，勞即牢固，字之誤耳。妄執延年，故云妄延。

The physical body with its sense faculties is unreal and inherently impermanent; it truly cannot be craved as lasting. Now, craving it firmly and falsely clinging to longevity, it is termed 'the attachment to craving what is not to be craved.' 'Asita' means peerless, referring to the long-lived ṛṣis. As for 'the fruit of prolonged weariness,' weariness (勞) stands for solidity (牢), an error of character. Falsely clinging to prolonging years, it is called 'falsely prolonged.'
