When I was younger, I was terrified to express anger because it would often kick-start a horrible reaction in the men in my life. So I bit my tongue. I was left to painstakingly deal with the aftermath of my avoidance later in life, in therapy or through the lyrics of my songs.
In the march towards Truth, anger, selfishness, hatred, etc., naturally give way, for otherwise Truth would be impossible to attain. A man who is swayed by passions may have good enough intentions, may be truthful in word, but he will never find the Truth.
There are those who discover they can leave behind destructive reactions and become patient as the earth, unmoved by fires of anger or fear, unshaken as a pillar, unperturbed as a clear and quiet pool.
