Commentary by Pir-o-Murshid Inayat KhanAll planes of existence consist of vibrations, from the finest to the grossest kind; the vibrations of each plane have come from a higher one, and have become grosser. Whoever knows the mystery of vibrations, he indeed knows all things. ... From the scientific standpoint, spirit and matter are quite different from each other, but according to the philosophical point of view they are one. Spirit and matter are different, just as water is different from snow; yet again they are not different, for snow is nothing other than water. When spiritual vibrations become more dense they turn into matter, and when material vibrations become finer they develop into spirit.

If it were not for vibration, the precious stones would not show us their color and their brilliance; it is vibration which makes the tree grow, the fruit ripen, and the flowers bloom. Our existence is also according to the law of vibrations, not only the existence of our physical body but also our thoughts and feelings. ... When we begin to see life from this point of view it will appear that birth and death are only our conceptions of life, that there is no such thing as death and that all is living. It only changes from one form to the other, subject to the law of vibrations.
