觀無量壽佛經義疏 3.247

3.247

"At that time Ānanda arose from his seat, stepped forward, and said to the Buddha: ‘World-Honoured One, what should this sūtra be named? How should the essentials of this Dharma be accepted and upheld?’" Asking first about the name of the sūtra and second about the method of upholding, hence it is called asking both. Second, replying separately has two parts: first, showing the name; second, teaching its upholding. First, showing the name has two parts: first, naming it based on the contemplating subject and contemplated object; second, naming it with reference to its efficacy. First, naming it based on the contemplating subject and contemplated object.
