I think that the body is what traps the mind.

Let me explain...

The mind is an entirely separate entity from the body, and it controls the body for the most part. The body is very complex, but very simple compared to the mind, which is 100 times more intricate. The body can be killed simply by loss of blood, no oxygen, etc....the mind, however, is indestructable, and when the body dies, the mind is free to experience sensation free from perception.

By that theory of mine, death is freedom, but of a very bittersweet sort...enjoy your grounded life with a body as much as possible before it is snuffed out.
