If you practice metta meditation to a certain level,
anger will not arise easily but does not mean it will not
arise. One's mind will also have better concentration and
gain samadhi - the mind is clearer to discern what is wrong or
right.
I faced the same problem at work too but bo bian, need to ignore
and work out a solution to deal with it. Sometime, anger and even
murderous thought arise the whole day. However, office politics are
actually quite common everywhere. I accept it liao.Treat it
like cultivating your paramitas of forbearance. It will be good to
learn to forgive and forget.
Also remind me of a story, when someone insult the buddha,
buddha also not affected. When someone ask Budda why he is not
angry. Buddha said if someone gives u a gift, if you don't accept
it, you are not accepting the gift. Similary when
someome try to hurl insult, you don't have to acknowledge
it.
When someone gossip/taichi stuffs, No need to feel frustrated..
If you do more, you will learn more. Gossip are wandering
talks. Sometime it is not based on who you are but what they
interpreted. As such u should know yourself best.
Cheers
