Conversation enriches the understanding, but solitude is the school of genius.
Meditation tends to lower or normalize the blood pressure, pulse rate, and the levels of stress hormones in the blood. In short, it reduces wear and tear on both body and mind, helping people live better and longer. My psychologist thought so too, and suggested I take it up. It seemed like instead of re-charging me it was just using up precious mental and physical energy that I really needed to use for survival. Already found you can't use meditation with worn out people, it takes too much energy and they need to use what they have for other purposes.
