“Intensity, secrecy, devotion, and constancy are necessary. You don’t know when death will come. Every minute keep your mind on God. Everything you want and need is right within you; seek long and seek deeply. I meditate for hours; I see no one until I am finished. You must make up your mind that you are not going to be bothered by anyone or anything. Then you won’t know time. That is the only way to find Him. Don’t waste your time. When you are able to live in the divine consciousness, four to six hours of sleep are plenty; you will never feel tired, you will never miss sleep. Sleep is under my control; it is the same with eating. I have something infinitely greater.”
