觀無量壽佛經義疏 3.54

3.54

「『是為像想，名第八觀。』」準上經文，明列三像。或謂二菩薩無像觀者，未知何意？三、顯益。

" 'This is the visualization of the images, called the eighth contemplation.'" According to the sūtra text above, it clearly lists three images. As for those who claim there is no contemplation of images for the two bodhisattvas, one does not know what their reasoning could be. Third, revealing the benefits.
