Spiritual leader with little time for talk (6)
I believe the answer is:
rabbit
'talk' is the definition.
(rabbit can informally mean to talk)
'spiritual leader with little time' is the wordplay.
'spiritual leader' becomes 'rabbi' (Jewish teacher).
'with' is a charade indicator (letters next to each other).
'little time' becomes 't' (abbreviation for time).
'rabbi'+'t'='RABBIT'
'for' acts as a link.
(Other definitions for rabbit that I've seen before include "Poor player" , "Furry rodent" , "Bit bar (anag.)" , "Fur; chatter (colloq.)" , "bun?" .)
