So a voice in the mountain is enough to let loose an avalanche. A word too much may be followed by a caving in. If the word had not been spoken, it would not have happened.
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.
One cannot completely get rid of the six passions: lust, anger, greed, and the like. Therefore one should direct them to God. If you must have desire and greed, then you should desire love of God and be greedy to attain Him.
The man who gives way to anger, or hatred, or any other passion, cannot work; he only breaks himself to pieces, and does nothing practical. It is the calm, forgiving, equable, well-balanced mind that does the greatest amount of work.
The man that is dominated by Anger Doth not know what is seemly and seeth not the Law; That man whom Hate doth accompany, Becometh like unto murky darkness.
As soon as we react, we become slaves. A man blames me, and I immediately react in the form of anger. A little vibration which he created made me a slave.
Evil company is always to be shunned; because it leads to lust and anger, illusion, forgetfulness of the goal, destruction of the will (lack of perseverance), and destruction of everything. (Narada Bhakti Sutra)
