Thirty Discourses on Giving and Support for the Womb-born and So On
362-391.
At Sāvatthī.
Seated to one side, that monk said this to the Blessed One -
"What, venerable sir, is the cause, what is the condition, whereby someone here, upon the body's collapse at death, is reborn in the company of womb-born serpents?" Etc.
"in the company of moisture-born serpents?" Etc.
"is reborn in the company of spontaneously born serpents?"
"Here, monk, someone acts in two ways by body, acts in two ways by speech, acts in two ways by mind. He has heard: 'Spontaneously born serpents are long-lived, beautiful, and abounding in happiness.' He thinks thus: 'Oh, may I, upon the body's collapse at death, be reborn in the company of spontaneously born serpents!' He gives food, etc. he gives drink, etc. he gives material for lighting. He, upon the body's collapse at death, is reborn in the company of spontaneously born serpents. This, monk, is the cause, this is the condition, whereby someone here, upon the body's collapse at death, is reborn in the company of spontaneously born serpents."
