The hylic or Somatic vs. psychic distinction, held as true by gnostics, is a very questionable approach to spirituality. The most thorough work done on this issue is by the Buddha. The most popular Hindu belief of his time was parallel to this gnostic idea, it held that the soul (atman in Skt., Greek psyche) must be freed from the material through practices of yoga.
He tried. He found it didn't work. He rejected the whole approach. We don not need to separate mind and matter. We need to use Mind to become Aware of all that is, both Mind and Matter. That is most effective path to liberation I have found in a lifetime of study.
