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 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.
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.
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.
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.
