觀無量壽佛經疏 1.30

1.30

Namely, there are differences at the time of departure among these three grades. How are they different? When the superior-upper departs, the Buddha together with countless transformation Buddhas simultaneously extend their hands. When the superior-middle departs, the Buddha together with one thousand transformation Buddhas simultaneously extend their hands. When the superior-lower departs, the Buddha together with five hundred transformation Buddhas simultaneously extend their hands. It is simply that karma has strength and weakness, which causes there to be these distinctions!
