法華義疏 8.334

8.334

「生已度想生安穩想」者，第三句，證涅槃果也。出三界生死名生已度想，證無餘涅槃生安穩想。又得有餘名已度想，入無餘名安穩想。又得盡智名已度想，得無生智名安穩想。實非究竟謂是究竟，故稱為想。

"Gave rise to the thought that they had already crossed over, and gave rise to the thought of peace and stability" is the third phrase, realizing the fruit of nirvāṇa. Leaving the saṃsāra of the three realms is called giving rise to the thought that they had already crossed over; realizing nirvāṇa without remainder is giving rise to the thought of peace and stability. Furthermore, attaining nirvāṇa with remainder is the thought of having already crossed over; entering nirvāṇa without remainder is the thought of peace and stability. Again, attaining kṣayajñāna is the thought of having already crossed over; attaining anutpādajñāna is the thought of peace and stability. In reality it is not ultimate, yet they consider it ultimate; therefore it is called a "thought".
