Compassion is not against anger. When anger disappears, compassion is. Compassion is not to be fought for; it is not against passion. When passion disappears, compassion is. Compassion is your nature.
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.
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.
