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.
Silence and stillness are not states and therefore cannot be produced or created. Silence is the non-state in which all states arise and subside. Silence, stillness and awareness are not states and can never be perceived in their totality as objects. Silence is itself the eternal witness without form or attributes. As you rest more profoundly as the witness, all objects take on their natural functionality, and awareness becomes free of the mind's compulsive contractions and identifications. It returns to its natural non-state of Presence.
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.
Perception without the word, which is without thought, is one of the strangest phenomena. Then the perception is much more acute, not only with the brain, but also with all the senses. Such perception is not the fragmentary perception of the intellect nor the affair of the emotions. It can be called a total perception, and it is part of meditation.
It is more than probable that I am not understood; but I fear, indeed, that it is in no manner possible to convey to the mind of the merely general reader, an adequate idea of that nervous intensity of interest with which, in my case, the powers of meditation (not to speak technically) busied and buried themselves, in the contemplation of even the most ordinary objects of the universe.
If you are a meditator, as your meditation goes on becoming more and more luminous, your intelligence will be growing to the last breath of your life. Not only that, even after the last breath your intelligence will continue to grow - because you are not going to die, only your body will be dying. And the body has nothing to do with intelligence, mind has nothing to do with intelligence. Intelligence is the quality of your awareness - more aware, more intelligent. And if you are totally aware, you are as intelligent as this whole existence is.
If you determine your course With force or speed, You miss the way of the dharma. Quietly consider What is right and what is wrong. Receiving all opinions equally, Without haste, wisely, Observe the dharma.
If you were only to listen, it becomes meditation. Without meditation you cannot hear. What is the meaning of meditation? Meditation exists only where mind is not; where the internal dialogue is gone.
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 means the mind is turned back upon itself. The mind stops all the thought-waves and the world stops. Your consciousness expands. Every time you meditate you will keep your growth.
