…The peace for which you are hankering in life after life, moment after moment—that you’ll get at that time, when your desires are purified, and dovetailed with the Lord. One who desires sense gratification, the enjoyment of material satisfaction, will never be happy. That is not possible. If you want peace, if you want happiness, if you want perfection in your life, then just begin to dovetail your desires, activities, and potentials with the Supreme Personality of Godhead. Then you will see what real happiness is, and can tell who is really crazy.
Who Is Crazy? (Original)
by Swami A.C. Bhaktivedanta
Lord Sri Krishna says, “My dear Arjuna, there are different classes of men. One class of men, they are sleeping. And another class of men, they are awake. They are not sleeping.” And how is this so? This chanting, which we have performed just now, is the wakening process for the sleeping soul. The soul is sleeping, covered by this material body. These bodily activities are in the sleeping stage. Just as we see dreams in the sleeping stage, similarly, all these bodily activities are dreams. Just think for yourself: how many incidents have there been in your past life? If you think of them, they will appear just like dreams. At least for myself this is the case. I was born in India, educated, then married, then I had very good days with my wife, got some children, some of whom died, some of whom are living, some of whom are married; now they have begotten children. All this occurred in my past life. Now it is all a dream. I have no connection with it. Similarly, in dreams I sometimes find that I have become a king. Oh, there are so many riches and so much opulence. Then, as soon as the dream is over, I come home and all is gone.
