觀無量壽佛經義疏 3.126

3.126

「『但想佛像，得無量福，況復觀佛具足身相。』」想像獲福，觀真可知。四、身量不定。

"‘Merely visualizing the Buddha's image yields immeasurable merit; how much more so contemplating the complete physical marks of the Buddha!’" If visualizing an image obtains blessings, contemplating the real one can be known. Fourth, the indeterminate size of the body.
