1Then a number of bhikkhus approached the Blessed One, paid homage to him, sat down to one side, and said to him: "Venerable sir, what now is spiritual power? What is the basis for spiritual power? What is the development of the bases for spiritual power? What is the way leading to the development of the bases for spiritual power?"

The Buddha’s answers are exactly the same as in §19. sn.v.288

1Atha kho sambahulā bhikkhū yena bhagavā tenupasaṅkamiṁsu; upasaṅkamitvā bhagavantaṁ abhivādetvā ekamantaṁ nisīdiṁsu. Ekamantaṁ nisinnā kho te bhikkhū bhagavantaṁ etadavocuṁ: "katamā nu kho, bhante, iddhi, katamo iddhipādo, katamā iddhi pāda bhāvanā, katamā iddhi pāda bhāvanāgāminī paṭipadā"ti?

2"Idha, bhikkhave, bhikkhu anekavihitaṁ iddhividhaṁ paccanubhoti – ekopi hutvā bahudhā hoti … pe … yāva brahmalokāpi kāyena vasaṁ vatteti – ayaṁ vuccati, bhikkhave, iddhi.

3Katamo ca, bhikkhave, iddhipādo? Yo, bhikkhave, maggo, yā paṭipadā iddhilābhāya iddhipaṭilābhāya saṁvattati – ayaṁ vuccati, bhikkhave, iddhipādo.

4Katamā ca, bhikkhave, iddhi pāda bhāvanā? Idha, bhikkhave, bhikkhu chandasamādhippadhānasaṅkhārasamannāgataṁ iddhi pādaṁ bhāveti, vīriyasamādhi … pe … cittasamādhi … vīmaṁsāsamādhippadhānasaṅkhārasamannāgataṁ iddhi pādaṁ bhāveti – ayaṁ vuccati, bhikkhave, iddhi pāda bhāvanā.

5Katamā ca, bhikkhave, iddhi pāda bhāvanāgāminī paṭipadā? Ayameva ariyo aṭṭhaṅgiko maggo, seyyathidaṁ – sammādiṭṭhi … pe … sammāsamādhi – ayaṁ vuccati, bhikkhave, iddhi pāda bhāvanāgāminī paṭipadā"ti.

Navamaṁ.
