All human beings have an innate desire to overcome suffering, to find happiness. Training the mind to think differently, through meditation, is one important way to avoid suffering and be happy.
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.
Happiness, whether consisting in pleasure or virtue, or both, is more often found with those who are highly cultivated in their minds and in their character, and have only a moderate share of external goods, than among those who possess external goods to a useless extent but are deficient in higher qualities.
In awareness there is no becoming, there is no end to be gained. There is silent observation without choice and condemnation, from which there comes understanding.
Meditation, you know, comes by a process imagination. You go through all these processes purification of the elements - making the one melt the other, that into the next higher, that into mind, that into spirit, and then you are spirit.
