Meetings that raise the spirits (7)
I believe the answer is:
seances
'meetings' is the definition.
(seance is a kind of meeting)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for seances that I've seen before include "Spiritualist's sittings" , "Spiritual meetings conducted by mediums." , "Meetings of spiritualists" .)
