There is the same tendency in human beings. Although the human being has much interest in life through his various occupations and various moods, he finds a thousand and one excuses for his restlessness, for his depression. And illusion is so much developed in man that a reason always comes at his command. There is always someone that will say to a poor man, "It is sad for you that you are not rich." Someone comes and says, "You look depressed. I know there is so much sorrow, that is the reason." But reason is always at his command and is employed without, and so man cannot find the real reason that is within. That reason is suppressed beneath all the reasoning, and man seeks more than the animal kingdom does to get back something that has been lost.
