'''Sweet Mother, '''
'''I have noticed one thing: When I sit for a few minutes and make an effort to concentrate before going to sleep, the next day I wake up quite early and am quite fresh. I concentrate on the tiny luminous tip of an incense-stick. But how is it that I wake up early because of that? There is no relation between these two things! '''
On the contrary, there is a very concrete relation. When you concentrate before sleeping, then in your sleep you remain in contact with the Divine force; but when you fall heavily to sleep without any preliminary concentration, you sink into the inconscient and the sleep is more tiring than restful, and it is difficult to come out of this sluggishness.
