In the simile of the saw, the Buddha points out that even if one were to be severed limb by limb, he who gives into anger, would not be practises his Teaching, let alone those who give in to anger because of minor issues I.e unwelcomed speech.
I believe, here, that the Buddha gives us a measurement by which to measure our progress or dedication i.e if you give in to anger then you are not practising.
Which therefore indicates the severity of the practise,or the seriousness of what needs to be done i.e the attitude that one should have.
The attitude of ‘I will not give in to anger no matter what’.
If one gives in to anger due to minor issues, it’s unlikely that when an intense situation arises that one will not do the same; and by NOT giving in to anger in regards minor issues,one can build up a resolve in the face of anger i.e anger might arise but one does not GIVE IN/ indulge it or welcome it, so that when intense situation arises one has the developed strength to overcome it,to endure it equanimous.
He also seems to suggest that , practising the Dhamma/not giving in to anger ,does not protect you physically from unfortunate circumstances but can result in equanimity in regards to the most horrific type of incidents.
Should one think that one is ‘on the path’ if one gets angry over matters e.g someone calling you an idiot, not getting your coffee on time, or having a headache etc? And if one is getting angry over trivial matters,then how serious are you about the practise?
I would have to say that getting angry or giving in to or welcoming anger,one is not serious about the practice,
What do think? Did the Buddha mean something different?
