Āsīvisasutta untranslated

Āsīvisasutta 01. Preached at Sāvatthī. Man has to tend four snakes of fierce heat and fearful venom – the four mahābhūtas; be is constantly followed by five murderous foes – the five upādānakkhandhā; he is pursued by a murderous housebreaker with uplifted sword – passionate desire (nandirāga); while trying to escape them, he wanders into an empty village, where everything is empty – the sixfold personal sense sphere (ajjhattikāyatana), and into it come village-plunderers – the six fold external sense-spheres (bāhirāyatana.) Fleeing from there he comes to a broad sheet of water beset with danger on the hither side; the further side is secure from fear, but there is no boat and no bridge – the fivefold flood (ogha), the hither shore being sakkāya and the further shore Nibbāna. SN.iv.172-b.

Āsīvisasutta 02. There are four kinds of snakes in the world: the venomous but not fierce, the fierce but not venomous, the one that is both and the one that is neither. Similarly there are four kinds of persons: the one quick to get angry but with short-lived anger, the one slow to get angry but with lasting anger, etc. (AN.ii.110-11)
