My religion teaches me that I should, by my personal conduct, instill into the minds of those who might hold different views the conviction that cow killing is a sin.
Nothing divine dies. All good is eternally reproductive. The beauty of Nature re-forms itself in the mind, and not for barren contemplation, but for new creation.

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.
