Brahman is beyond mind and speech, beyond concentration and meditation, beyond the knower, the known and knowledge, beyond even the conception of the real and unreal. In short, It is beyond all relativity.
Meditation is like a single log of wood. Insight and investigation are one end of the log; calm and concentration are the other end. If you lift up the whole log, both sides come up at once. Which is concentration and which is insight? Just this mind.
To concentrate is not to meditate, even though that is what most of you do, calling it meditation. And if concentration is not meditation, then what is? Surely, meditation is to understand every thought that comes into being, and not to dwell upon one particular thought; it is to invite all thoughts so that you understand the whole process of thinking.
In the Buddha's life story we see the three stages of practice: Morality comes first, then concentrated meditation, and then wisdom. And we see that the path takes time.
Meditation, you know, comes by a process imagination. You go through all these processes purification of the elements - making the one melt the other, that into the next higher, that into mind, that into spirit, and then you are spirit.
Make your meditation a continuous state of mind. A great worship is going on all the time, so nothing should be neglected or excluded from your constant meditative awareness.
