There are those who imagine that the unlucky accidents of lifelife's "experiences"are in some way useful to us. I wish I could find out how. I never know one of them to happen twice. They always change off and swap around and catch you on your inexperienced side.
It is easy to remove the mind from harping on the lost illusion of immortality. The disciplined intellect fears nothing and craves no sugar-plum at the day's end, but is content to accept life and serve society as best it may. Personally I would not care for immortality in the least. There is nothing better than oblivion, since in oblivion there is no wish unfulfilled. We had it before we were born, yet did not complain. Shall we whine because we know it will return? It is Elysium enough for me, at any rate.
