Practise meditation perhaps every month, for example (5)
I believe the answer is:
dozen
'every month for example' is the definition.
(there are 12 months in a year)
'practise meditation' is the wordplay.
'practise' becomes 'do' (synonyms).
'meditation' becomes 'zen' (Zen is a type of Buddhist meditation).
'do'+'zen'='DOZEN'
'perhaps' is the link.
(Other definitions for dozen that I've seen before include "See 4" , "One less than 13" , "Twelfth of a gross" , "Quantity of e.g. eggs" , "A small number" .)
