Meditation is not a process of learning how to meditate; it is the very inquiry into what is meditation. To inquire into what is meditation, the mind must free itself from what it has learnt about meditation, and the freeing of the mind from what it has learnt is the beginning of meditation.
Don't think that any one technique is the end. there is no end. There is no perfect technique. Just when you think you've got them, you're dead because you didn't.
