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.
When the mind goes beyond the thought of 'the me,' the experiencer, the observer, the thinker, then there is a possibility of a happiness that is incorruptible.
What are you thinking of so earnestly?" said he, as they walked back to the ballroom; "not of your partner, I hope, for, by that shake of the head, your meditations are not satisfactory." Catherine coloured, and said, "I was not thinking of anything." That is artful and deep, to be sure; but I had rather be told at once that you will not tell me." Well then, I will not." Thank you; for now we shall soon be acquainted, as I am authorized to tease you on this subject whenever we meet, and nothing in the world advances intimacy so much.
Whenever you aren’t manipulating your experience, you’re meditating. As soon as you meditate because you think you should, you’re controlling your experience again, and you’ve squeezed all the value out of your meditation.
In true meditation the emphasis is on being awareness; not on being aware of objects, but on resting as primordial awareness itself. Primordial awareness is the source in which all objects arise and subside. As you gently relax into awareness, into listening, the mind's compulsive contraction around objects will fade. Awareness naturally returns to its non-state of absolute unmanifest potential, the silent abyss beyond all knowing.
Regarding this Dhamma, it is not something that we can simply talk about or take another's word for it. We need to develop meditation so that the understanding arises clearly within oneself. It is not the case that merely by listening to another's explanation our defilements will disappear. When we gain some understanding we need to chew on it again so that we see it for ourselves with certainty: paccattam.
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.
