"The Body of Liberation has a Christic appearance. It exudes the aroma of perfection. This body replaces the physical body; it is made of flesh, but it is not the born from the flesh of Adam. This is the body of paradisiacal beings; this body is not submitted to illnesses or death." - Samael Aun Weor, The Major Mysteries "
"We extract the body of liberation from the physical body. This body is made with flesh, but flesh that does not come from Adam. It is a body filled with millenarian perfections. It is elaborated with the most evolved atoms of our physical body. [...] The body of Liberation is neither subjected to sickness, nor to death. The body of Liberation is made with flesh and bones, but it is flesh that does not come from Adam. It is flesh from the Cosmic-Christ. The body of Liberation is similar to the Divine Rabbi of Galilee. The body of Liberation is the body of the Gods." - Samael Aun Weor, Treatise of Sexual Alchemy
"The body of liberation converts us into citizens of Eden." - Samael Aun Weor, Igneous Rose
