People say you can help everyone to start getting soul (6)
I believe the answer is:
Here is my best explanation:
'soul' is the definition.
('psyche' can be a synonym of 'soul')
'people say you can help everyone to start' is the subsidiary indication.
'to start' suggests taking the first letters.
The initial letters of 'people say you can help everyone' is 'psyche'.
'getting' is the link.
(Other definitions for psyche that I've seen before include "Princess beloved by Cupid", "The beloved of Eros", "The mind or Cupid's lover", "Human soul, or its personification in female form", "Wife of Cupid", "Eros's beloved", "The human mind/spirit", "Soul - girl from Greek mythology", "Human soul or spirit" and "The immaterial part of a person".)
