觀無量壽佛經疏 2.86

2.86

八、從唯願世尊已下，正明夫人請求別行。此明韋提既選得生處，還修別行勵己注心，必望往益。言教我思惟者，即是定前方便，思想憶念彼國依正二報、四種莊嚴也。言教我正受者，此明因前思想漸漸微細覺想俱亡，唯有定心與前境合，名為正受。此中略已料簡，至下觀門更當廣辯。應知。

Eighth, from "I only pray that the World-Honoured One..." down, it clearly shows that the consort requested the specific practice. This clarifies that once Vaidehī had chosen the place of rebirth, she turned back to cultivate the specific practice, urging herself on and focusing her mind, firmly hoping for the benefit of rebirth. The phrase "Teach me to ponder" refers to the preliminary expedients prior to concentration, thinking of and recollecting the two retributions—circumstantial and primary—of that land, and the four kinds of adornments. The phrase "Teach me samāpatti" clarifies that, relying on the preceding thoughts, contemplation gradually becomes subtle until both thoughts and perceptions are extinguished, and only the concentrated mind unites with the preceding object; this is called samāpatti. A brief assessment has already been made here; in the contemplation gates below, it will be analyzed more extensively. This should be known.
