Meditation is not a deal of knowledge. One can collect knowledge but not meditation. So there are no levels like beginner, intermediate, advanced etc. in meditation. There are just states; it is meditation or it is not. Meditation cannot be collected; it means there is nothing to achieve in it. It is always new due to its non-collective nature. It is as new that one cannot practice it. Practice indicates adding more and more every day to something. In meditation, everything is there and after meditation nothing left behind. So there is nothing to practice and nothing to add more. It is always fresh, always a new beginning without the interference of past; so is sacred and pure.
