此經心觀為宗、實相為體。所言佛說觀無量壽佛者，佛是所觀勝境，舉正報以收依果、述化主以包徒眾。觀雖十六，言佛便周，故云佛說觀無量壽佛。經者，訓法訓常，由聖人金口故。

This sutra takes mind-contemplation as its principle and true mark as its substance. As for the words 'The Buddha Speaks of the Contemplation of the Buddha of Immeasurable Life,' 'Buddha' is the supreme realm to be contemplated; raising the primary reward encompasses the circumstantial fruition, and narrating the converting master includes the retinue of disciples. Although the contemplations are sixteen, mentioning the Buddha makes it complete; hence it is called 'The Buddha Speaks of the Contemplation of the Buddha of Immeasurable Life.' 'Sutra' means standard and constancy, because it came from the golden mouth of the Sage.
