Teacher of the Dharma (4)
I believe the answer is:
lama
'teacher of the dharma' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for lama that I've seen before include "Tibetan high priest" , "Religious leader" , "devout Buddhist" , "A Buddist monk in Tibet" , "A Tibetan Buddhist priest or monk" .)
