Osho says, in his book, 'Meditation, the first and last Freedom'
"In fact, there are 112 methods of meditation. I have gone through all of those methods - not intellectually. It took me years to go through each method and to find out its very essence. And after going through one hundred twelve methods, I was amazed that the essence is witnessing; the methods' non-essentials are different, but the centre of each is witnessing." ~Osho
