True Brahmin Will not angry .... chanakya is the best example for real brahmin ... don't anger .. if u get anger, don't show that ... post pone your anger for 15 minutes... this is the technique .... try this ..
Dear Sir,
Anger is a normal human response.
Even children display this.
Try taking a toy away from a child and he might display short lived anger and then cry.
But if we distract him with another toy..he smiles right away.
So being 100% anger free is not possible under normal circumstance.
We are only able to either cool down fast or try to divert our mind.
Very few people are 100% anger free..(most of those I know who are anger free are in the psychiatric ward... they keep smiling and laughing all the while and do not get angry even when provoked. I am not kidding)
In fact in our Puranas we see uncontrollable bouts of anger of even sages/munis/brahmins too and they keep cursing everyone that rubs them the wrong way.
Even the famous Ratnakara who became Valmiki did not spare the hunter who killed one of the pair of mating Krauncha birds.
Valmiki himself had been a highway robber before and had injured people in the past but yet he chose to curse the hunter instead of guiding him to not kill mating birds.
Sages in our Puranas seldom displayed total Sattva behavior.
I can also think of a medical situation that can make people irritable and angry.
Long term vegan/vegetarian diet at times can lead to Vitamin B 12 deficiency and this can make a person very moody and irritable.
So as vegetarians we should make sure we at least take a Vit B12 supplement or take soya based food.
