John Dryden wrote in the seventeenth century:
Death in itself is nothing; but we fear
To be we know not what, we know not where.Aurengzebe,Act IV,Scene 1;
Although human beings seem to die, somewhere in each of us is the hope of immortality. And there is the conviction that our happiness or misery in any possible afterlife is dependent upon our good or bad behavior here. What we fear, perhaps, is not so much passing through the portal called death as becoming "we know not what" in another world "we know not where."
