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.
But people of the deepest understanding look within, distracted by nothing. Since a clear mind is the Buddha, they attain the understanding of a Buddha without using the mind.
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.
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.
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.
Walk, but make walking a meditation; walk knowingly Breathe, but let your breathing become a constant meditation; breathe knowingly. The breath going in: watch it. The breath going out: watch it. Eat, but eat with full awareness. Take a bite, chew it, but go on watching. Let the watcher be there in every moment, whatsoever you are doing.
