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.
Proper effort is not the effort to make something particular happen. It is the effort to be aware and awake each moment, the effort to overcome laziness and merit, the effort to make each activity of our day meditation.
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.
Just as I sit down to meditate, all the vilest subjects in the world come up. The whole thing is nauseating. Why should the mind think thoughts I do not want it to think? I am as it were a slave to the mind.
