3.317

[Kumāra]jīva says: "There was an arhat named Vakkula who, in the past, was a medicine seller. He said to the monks observing the summer retreat: 'If anyone needs medicine, come to me and take it.' The community ended up needing nothing; only one monk had a slight illness and received a single harītakī fruit. Because of this, for ninety kalpas he was born among gods and humans, enjoying immeasurable bliss; he only heard the name of illness, yet his body never suffered the slightest affliction. In his present life, he was already ninety years old and had never experienced sickness. How much less so for the Buddha, who has accumulated immeasurable good deeds—how could illness arise in him? A question asks: 'Good and evil are opposites, and their retributions should correspond. One who commits the grave crime of the five heinous sins suffers torment for an entire kalpa; how can the good deed of a single fruit bring immeasurable blessings?' The answer says: 'The act of sin is heavy, but its power is weak; the act of good is light, but its force is potent. It is like a venomous snake about to capture a human for food: it first spits toxic froth upon the ground. When the human steps on it, they instantly fall into a stupor, unable to get up and leave, after which it draws them in with its breath. Performing meritorious deeds within the Three Jewels is also like this: when one first performs a meritorious deed, though the matter is slight, the hidden benefit is already profound; afterward, through upāya, one is guided into the Buddha Path, and only upon reaching ultimate nirvāṇa is that blessing exhausted.'"
