Human mind or spirit (6)
I believe the answer is:
psyche
I believe this clue is a double definition.
'human mind' is the first definition.
(I've seen this in another clue)
'spirit' is the second definition.
(psyche can mean spirit or soul)
(Other definitions for psyche that I've seen before include "Immaterial part of a person" , "Innermost self" , "Individuality" , "The mind or Cupid's lover" , "Human soul - Cupid's beloved" .)
