Change during meditation (4)
I believe the answer is:
'change' is the definition.
(edit can mean to change or alter)
'during meditation' is the wordplay.
'during' indicates a hidden word.
'EDIT' is hidden in the letters of 'meditation'.
(Other definitions for edit that I've seen before include "Revise text" , "Make textual changes" , "Alter text" , "Revise for publication" , "Ready for publication" .)
