Death and creation
Thelema has no fables or supernatural beliefs about any form of life after death. It teaches that death really is death, and that far from being a curse, mortality is something more akin to a gift. An immortal soul would offer no hope of escape or relief; it would be horrible eternal bondage. Thelema teaches that death is the cessation of all worry and toil, the ultimate freedom, and the perfect rest.
Moreover, it is only mortality that gives life any meaning. With an immortal soul, we would have an infinite amount of time to do an infinite amount of things, no matter how long we waited to get started. Therefore, it is hard to see how there could ever be any motivation to do anything. A finite amount of life gives our choices meaning, because every choice reduces the number of choices that we have remaining. Our actions and our choices determine what we are, and with a finite amount of choices available to us, each choice and each action becomes an expression of individuality, a joyous statement of essential being, which provides the Thelemite's motivation.
Thelema also has no fables or supernatural beliefs about the creation of the universe and the origins of life. Such questions are considered to be the domain of science rather than religion, and when no scientific answer currently exists, it is not considered sensible to insert imaginary religious “answers” in their place.
