If anger flares up in you and you have no technique for dealing with it, other than punishing yourself and others, then this book is for you. Bhuddist psychology is not quackery or pseudo-science, it's practicle and applicable to everyday life. I have met the author, and he genuinely lives the life that he recommends to you - a life of love and compassion for yourself and others.
By the end of this book I saw the suffering that I have caused myself and loved ones through my anger, and the futility of holding onto it with righteous pride. Anger is suffering, there is no nobility in it, just pain, and this book teaches you not to combat anger with yet more hatred and self loathing, but to transform it with wisdom and compassion.
