Spiritual charge provides the remedy (4)
I believe the answer is:
cure
This could be a double definition.
'spiritual charge' is the first definition.
'cure' can be an answer for 'charge' (thesaurus). I'm not sure about the 'spiritual' bit.
'the remedy' is the second definition.
('cure' can be a synonym of 'remedy')
'provides' acts as a link.
Can you help me to learn more?
(Other definitions for cure that I've seen before include "Make better - smoke" , "Remedy, therapy" , "Heal or pickle" , "Make well again" , "Restorative" .)
