又增一阿含經云。佛言。如是世間不可思議。如龍界不可思議。云何此雨為從龍口出耶。答不從龍口出。為從眼耳鼻身出耶。亦不從此出。但龍意所念。若念惡亦雨。若念善亦雨。亦由根本而作此雨。如須彌山。腹有天名曰大力。知眾生心之所念。亦能作雨。然雨不從彼天口眼耳鼻出也。皆由彼有神力故而作此雨。

Furthermore, the *Ekottarika-āgama* states: The Buddha said: "Just as this world is inconceivable, so the realm of nāgas is inconceivable. How does this rain fall—does it emerge from the nāga's mouth? Answer: It does not emerge from the mouth. Does it emerge from the eyes, ears, nose, or body? It also does not emerge from these. It is only what the nāga's mind thinks: if it thinks evil, it also rains; if it thinks good, it also rains. It is also through the fundamental cause that this rain is made. Just as on the slope of Mount Sumeru there is a deva named Great Strength who knows the thoughts in the minds of sentient beings and can also make rain, yet the rain does not emerge from that deva's mouth, eyes, ears, or nose; it is entirely because he possesses spiritual power that he makes this rain."
