Death - Words used in A Course in Miracles

Death is easy to define and hard to comprehend. 

There is no death, but there is a belief in death. T-3.VII.5:11.

The belief in death is the ego's attempt at making the dream, and thus itself, real.

When your body and your ego and your dreams are gone, you will know that you will last forever. Perhaps you think this is accomplished through death, but nothing is accomplished through death, because death is nothing. Everything is accomplished through life, and life is of the mind and in the mind. The body neither lives nor dies, because it cannot contain you who are life. If we share the same mind, you can overcome death because I did. Death is an attempt to resolve conflict by not deciding at all. Like any other impossible solution the ego attempts, it will not work. T-6.V.A.1. 

Judgment is but a toy, a whim, the senseless means to play the idle game of death in your imagination. ... What if you recognized this world is an hallucination? What if you really understood you made it up? What if you realized that those who seem to walk about in it, to sin and die, attack and murder and destroy themselves, are wholly unreal? Could you have faith in what you see, if you accepted this? And would you see it? Hallucinations disappear when they are recognized for what they are. T-20.VIII.7:1,3-7/8:1.
