Narrowness solidify "object me" I am so, I am this, I am that, woman, man, nun, monk, I am Nyingma, Sakya, Gelug, Jonang, Kagyu, rime..., buddhist.
Then subject something, someone is others, not so like me (characteristics).
No problem if aware, if not it is "me its' traps" of solidifying idea with creation of other ideas of all the wrongs and the goods and...Suffering self protection-cherishing and so on. gives patience less chance.
Just two cents.
