Cheating the Ferryman, Is there Life After Death, The Daemon.

CTF/ITLAD suggests a very specific structure as to what happens to human consciousness at the point of death. In his writings Anthony Peake also considers that all the elements of CTF can be found in Gnostic teachings. He proposes that the great Gnostic philosophers and writers of the past had an awareness of CTF and described it in esoteric language. The same applies to the great mystic and occult schools of Europe and Asia. Have you an opinion on this? Do you agree that writers such as Crowley, Blake, Blavatsky, Gurdjeif and Ouspensky (and many others) were describing elements of ITLAD in a different form. Was CTF the real secret of the Cathars?
