"Meditation starts by being separate from the mind, by being a witness. That is the only way of separating yourself from anything. If you are looking at the light, naturally one thing is certain: you are not the light, you are the one who is looking at it. If you are watching the flowers, one thing is certain: you are not the flower, you are the watcher. Watching is the key to meditation: watch your mind.
Don't do anything - no repetition of a mantra, no repetition of the name of god - just watch whatever the mind is doing. Don't disturb it, don't prevent it, don't do anything at all on your part. You just be a watcher, and the miracle of watching is meditation. As you watch, slowly, slowly mind becomes empty of thoughts, but you are not falling asleep, you are becoming more alert, more aware.
As the mind becomes completely empty, your whole energy becomes a flame of awakening. This flame is the result of meditation. So you can say that meditation is another name of watching, witnessing, observing -- without any judgment, without any evaluation." - Osho in "The Invitation"
