1. āsīvisa Sutta.-Preached at Sāvatthi.
Man has to tend four snakes of fierce heat and fearful venom -
  - the four mahābhūtas; he 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. 
S.iv.172-b.
2. āsīvisa Sutta.-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. (A.ii.110-11)
āsīvisa Vagga.-The nineteenth chapter of the Salāyatana Samyutta of 
the Samyutta Nikāya. J.iv.172-204.
