Regularly meditate as exercise (5,5)
I believe the answer is:
daily dozen
'exercise' is the definition.
(thesaurus)
'regularly meditate' is the wordplay.
'regularly' becomes 'daily' (I've seen this before).
'meditate' becomes 'dozen' (I am not sure about this - if you are sure you should believe this answer much more).
'daily'+'dozen'='DAILY DOZEN'
'as' acts as a link.
Can you help me to learn more?
(Other definitions for daily dozen that I've seen before include "Physical exercises done usually every morning" , "Regular exercises" .)
