Is it not a blasphemy to say that the world needs our help? We cannot deny that there is much misery in it; to go out and help others is, therefore, the best thing we can do, although in the long run, we shall find that helping others is only helping ourselves.

Life is good or evil according to the state of mind in which we look at it, it is neither by itself. Fire, by itself, is neither good nor evil. When it keeps us warm we say, "How beautiful is fire!" When it burns our fingers, we blame it. Still, in itself it is neither good nor bad. According as we use it, it produces in us the feeling of good or bad; so also is this world. It is perfect. By perfection is meant that it is perfectly fitted to meet its ends. We may all be perfectly sure that it will go on beautifully well without us, and we need not bother our heads wishing to help it.

Yet we must do good; the desire to do good is the highest motive power we have, if we know all the time that it is a privilege to help others.

And one must first know how to work without attachment, then one will not be a fanatic. When we know that this world is like a dog's curly tail and will never get straightened, we shall not become fanatics. If there were no fanaticism in the world, it would make much more progress than it does now. It is a mistake to think that fanaticism can make for the progress of mankind. On the contrary, it is a retarding element creating hatred and anger, and causing people to fight each other, and making them unsympathetic. We think that whatever we do or possess is the best in the world, and what we do not do or possess is of no value. So, always remember the instance of the curly tail of the dog whenever you have a tendency to become a fanatic. You need not worry or make yourself sleepless about the world; it will go on without you. When you have avoided fanaticism, then alone will you work well. It is the level-headed man, the calm man, of good judgment and cool nerves, of great sympathy and love, who does good work and so does good to himself.
