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.
God is the one goal of all our passions and emotions. If you want to be angry, be angry with Him. Chide your Beloved, chide your Friend. Whom else can you safely chide? Mortal man will not patiently put up with your anger; there will be a reaction. If you are angry with me I am sure quickly to react, because I cannot patiently put up with your anger. Say unto the Beloved, "Why do You not come to me; why do You leave me thus alone?" Where is there any enjoyment but in Him? What enjoyment can there be in little clods of earth?
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)
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.
The state exists for man, not man for the state. The same may be said of science. These are old phrases, coined by people who saw in human individuality the highest human value. I would hesitate to repeat them, were it not for the ever recurring danger that they may be forgotten, especially in these days of organization and stereotypes.
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.
