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 "Mind - soul", "A beautiful girl", "The mind or Cupid's lover", "Soul, mind, spirit", "Immaterial part of a person", "Spirit", "Human mind or spirit", "Beloved of Eros", "Human soul, or its personification in female form" and "The beloved of Eros".)
