People say you can help everyone to start getting soul (6)
I believe the answer is:
psyche
'soul' is the definition.
('psyche' can be a synonym of 'soul')
'people say you can help everyone to start' is the wordplay.
'to start' suggests taking the first letters.
The first letters of 'people say you can help everyone' is 'PSYCHE'.
'getting' acts as a link.
(Other definitions for psyche that I've seen before include "Core of one's personality" , "Human mind or spirit" , "Soul - girl from Greek mythology" , "inner spirit" , "Wife of Cupid" .)
