When we examine the differences in the responsive sightings of a Buddha's appearance in the world, they are due to the differences in whether sentient beings' practice is deep or shallow; hence there arises a disparity in how long or short an interval passes before they behold him. One hundred and thirty kalpas is for people of superior capacity; one hundred and eighty kalpas is for people of middling capacity; and 'in the past, immeasurable kalpas' is for people of inferior capacity. By briefly mentioning the differences of these three capacities, the principle of sympathetic resonance (ganying) is briefly encompassed.
