阿彌陀經通贊疏 3.28

3.28

As for 'the Sūtra of the Protection and Mindfulness by All Buddhas,' it refers to this very sūtra; according to this, its complete title should be 'Praise of the Inconceivable Merits of Amitābha Buddha,' but the text is abbreviated. 'The Sūtra of the Protection and Mindfulness by All Buddhas' means that the Buddhas protect, sustain, clearly remember, and are mindful of it; that is, although the multitude of practices is vast, it is difficult to equal the merits and blessings of recollecting the Buddha, yet many contend with the power of upholding this sūtra; therefore, it causes the Buddhas of the six directions to protect and uphold it with their spiritual power. The sages of worlds numerous as sands are mindful of it in a single thought; hence it is called 'the Sūtra of the Protection and Mindfulness by All Buddhas.'"
