"I find it necessary on the first page of this book, quite ready for publication, to give the following advice:"

“Remember you come here having already understood the necessity of struggling with yourself — only with yourself. Therefore thank everyone who gives you the opportunity.”

“It is the greatest mistake to think that man is always one and the same. A man is never the same for long. He is continually changing. He seldom remains the same even for half an hour.”

“Man has no permanent and unchangeable I. Every thought, every mood, every desire, every sensation, says "I.”

“A man may be born, but in order to be born he must first die, and in order to die he must first awake.”

“Only help him who is not an idler.”

“The power of changing oneself lies not in the mind, but in the body and the feelings. Unfortunately, however, our body and our feelings are so constituted that they don’t care a jot about anything so long as they are happy. They live for the moment and their memory is short. The mind alone lives for tomorrow. Each has its own merits. The merit of the mind is that it looks ahead. But it is only the other two that can "do.”
