Devas who cause sufficient rainfall and other favourable conditions.
Consequently, fruits and vegetables become deficient in nourishment and the
climate becomes irregular. As a result, people are exposed to ill-health and
become short-lived (see AN 4.70). In this way, those Buddhas who appeared in a
period of long lifespan enjoy longevity and those who appeared in a period of
short lifespan do not.
Though all Buddhas have the power to prolong their lives as a result of their past
deeds that have effected their conception, their lifespans are different in length.
According to the Chronicles of the Buddhas (
Buddha-vaṁsa
)
commentary which
says:
Upacita-puñña-sambhārānaṁ dīghāyuka-saṁvatta-niya-kamma-
samupetānam-pi Buddhānaṁ yuga-vasena āyuppamāṇaṁ
appamāṇaṁ ahosi.
Though they are endowed with the merits of their past deeds that can
bring about longevity as a result of their acquisition of wholesome
prerequisites, Buddhas are of unequal length of life in accordance with
their lifespans (
āyu-kappa
).
To give a worldly example: If the seed of a teak tree that has the ability to last
for 1,000 years is sown in a dry zone where the soil is hard and barren, it cannot
live that long. Similarly, the meritorious deeds of the Bodhisattas in their final
existence caused their conception and the power to prolong their lives. However,
if they attain Buddhahood in the short period of a lifespan (
āyu-kappa
), that is
like the dry, hard, barren land their lives have to be short according to their
lifespan.
Length of Lifespan When a Buddha Appears
Buddhas usually do not appear in an aeon when the lifespan of beings is on the
increase. Because if a Buddha were to appear in such an aeon and teach the
doctrine of impermanence and the like, beings would fail to understand the
characteristics of impermanence (
anicca
), suffering (
dukkha
) and the non-self
(
anatta
) of conditioned things as their lives become longer and longer, one aeon
after another. For this reason, Buddhas do not appear in any of the aeons on the
increase but they do so in the decreasing aeons.
Even with regard to the decreasing aeons, Buddhas appear only in the aeons that
have a lifespan of at most 100,000 years. They do not appear in the aeons that
