… bile, phlegm, wind, imbalance, climate, carelessness, assault …
These are strange causes. Or the translation is wrong.
Maybe the 3 sans are meant: greed, hate, ignorance …with these one generates (based on vipaka) san-vedana of anger (bile and assault), heaviness (phlegm and carelessness), restlessness (wind and imbalance) … ?
Or is it about the 5 niyama dhamma (dhammata)?
