One who wills the end wills also the means; in order to be able to do good work for the world he must develop within himself the necessary strength and the necessary qualities.

Therefore he who wishes to reform the world must first of all reform himself.

He must learn to give up altogether the attitude of insisting upon rights, and must devote himself utterly to the most earnest performance of his duties.

He must learn to regard every connection with his fellow-man as an opportunity to help that fellow-man, or in some way to do him good.
One who studies these subjects intelligently cannot but realize the tremendous power of thought, and the necessity for its efficient control.
All action springs from thought, for even when it is done (as we say) without thought, it is the instinctive expression of the thoughts, desires and feelings which the man has allowed to grow luxuriantly within himself in earlier days.
The wise man, therefore, will watch his thought with the greatest of care, for in it he possesses a powerful instrument, for the right use of which he is responsible.

It is his duty to govern his thought, lest it should be allowed to run riot and to do evil to himself, and to others; it is his duty also to develop his thought-power, because by means of it a vast amount of actual and active good can be done.
