佛說處處經 1.56

1.56

佛言：「阿羅漢飛行有二因緣故，令人不見：一者、恐人見便多供養；二者、恐惡人嫉妬之。」佛言：「現神足復有兩福：一者、人見飛行，便精進念道；二者、從人受施，令得大福用；是故現神足。意喜故便得大福。」

The Buddha said: 'When an arhat flies, there are two reasons why he makes himself unseen by people: first, for fear that if people see him, they will make lavish offerings; second, for fear that evil people will envy him.' The Buddha said: 'Displaying riddhipāda also brings two kinds of merit: first, when people see him flying, they will vigorously be mindful of the Way; second, receiving alms from people enables them to obtain great merit. It is for this reason that he displays riddhipāda. Because their minds are joyful, they obtain great merit.'
