He who begins by loving Christianity more than Truth, will proceed by loving his sect or church better than Christianity, and end in loving himself better than all.
Understanding transforms, it does not sublimate. If you understand, anger disappears and the same energy becomes compassion. Not that you sublimate: anger simply disappears, and the energy that was involved, invested in anger, is released and becomes compassion. When you understand hate, hate disappears and the same energy becomes love. Love is not against hate -- it is absence of hate.
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.
Chastity, non-injury, forgiving even the greatest enemy, truth, faith in the Lord, these are all different Vrittis. Be not afraid if you are not perfect in all of these; work, they will come. He who has given up all attachment, all fear, and all anger, he whose whole soul has gone unto the Lord, he who has taken refuge in the Lord, whose heart has become purified, with whatsoever desire he comes to the Lord, He will grant that to him. Therefore worship Him through knowledge, love, or renunciation.
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.
