Meditation is not something restricted to times of formal seated meditation; it is most fundamentally an attitude of being-a resting in and as being. Once you get the feel of it, you will be able to tune into it more and more often during your daily life. Eventually, in the state of liberation, meditation will simply become your natural condition.
Meditation is like the breeze that comes in when you leave the window open; but if you deliberately keep it open, deliberately invite it to come, it will never appear.
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.
The first thing to realize in meditation is that there is no authority, that the mind must be completely free to examine, to observe, to learn. And so there is no following, no accepting, no obedience.
Meditation is like the cloak of the good thief. You find a corner or somewhere where you can actually entertain your own self and your own soul, and understand what your work [is] here.
No thought, no action, no movement, total stillness: only thus can one manifest the true nature and law of things from within and unconsciously, and at last become one with heaven and earth.
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.
