5.103

【迦私】或迦尸。此云光，能發光故。釋迦世尊圓光一尋，阿彌陀佛光明無量。《智論》云：「無量有二種：一者實無量，二者有量之無量。」見第七卷。

[Kāśi] Or kāśi. This is translated as light, because it is capable of emitting light. Śākyamuni, the World-Honoured One, had an aura of one fathom, while Amitābha Buddha's light is immeasurable. The Treatise on Wisdom says: 'Immeasurability is of two kinds: first, real immeasurability; second, the immeasurability of that which has measure.' Seen in the seventh fascicle.
