I am sure the starter of this thread has his answers now.
Summary of that quote is this;
To live happily with people you got to first understand why they act as they do.
Majority of people walk around carrying lots of resentment,anger,regrets,failure,lack,
revenge etc. See those uni riots? if you talked to each individual,you will discover that they each have a story to tell.No excuse for obnoxious acts though, but that is where to begin-Listen and Understand.
People react differently when pressure is applied to them.While some go mia, others convert into a hurricane/tornado sweeping everybody and everything in it's path.
To socialize well with people and manage their fluctuating emotional threshholds we have to bear such issues in mind because their obnoxious acts is but a cry for help.
The same applies to the timid and most quiet.
They say that still waters run deep.True they do.
See,Whales and White sharks swim in the deep.
Now imagine for a minute attempting to cross the path of a quiet individual carrying 'whalish/sharkish isssues.'
Their obnoxious acts borders murder,homicide and suicide..
We often hear 'he/she was such a quiet person, never wronged anyone',always kept to himself/herself'whenever murder is reported.
..We just never knew what lay in the deep sea.
Once we bear such in mind we begin viewing obnoxious acts as sickness needing treatment and the individuals as patients.
Instead of judging, we emphathise,seek treatment and make them our friends until they normalize
Learn to be at peace with ALL and let your heart be at peace, not warring.
