Friends:

What are the 5 Ways to pacify Anger and Hate?

The Blessed Buddha once said:
There are, Bhikkhus & Friends, five methods to Quell Hate & Anger.
Which are these?
Towards any person against whom hatred and anger have arisen,
1: One should quickly direct mind to, cultivate and develop:
All-embracing, gentle and kind friendliness towards that person...
2: One should quickly direct mind to, cultivate and develop: 
compassion & pity ... mutual joy & ... indifferent equanimity ... or
3: One should avoid & not pay that person any attention at all ... or
4: One should remind oneself of the law of ownership of kamma or
5: One should know that this person too is the owner and inheritor
of his actions, that he is created by them, that his actions are his
future foundation, & that he will have both his good & bad actions
as his future... In these 5 ways one may overcome hate and anger...
