"If you desire wealth, and know at the same time that the whole world regards him who aims at wealth as a very wicked man, you, perhaps, will not dare to plunge into the struggle for wealth, yet your mind will be running day and night after money. This is hypocrisy and will serve no purpose. Plunge into the world, and then, after a time, when you have suffered and enjoyed all that is in it, will renunciation come; then will calmness come. So fulfil your desire for power and everything else, and after you have fulfilled the desire, will come the time when you will know that they are all very little things; but until you have fulfilled this desire, until you have passed through that activity, it is impossible for you to come to the state of calmness, serenity, and self-surrender. These ideas of serenity and renunciation have been preached for thousands of years; everybody has heard of them from childhood, and yet we see very few in the world who have really reached that stage. I do not know if I have seen twenty persons in my life who are really calm and non-resisting, and I have travelled over half the world."
