Say, lama's focus of thinking following mantra from the East (4)
I believe the answer is:
monk
'say' is the definition.
Although both the answer and definition are singular nouns, I can't see how one could define the other.
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for monk that I've seen before include "Trappist, for example" , "Thelonious - - (jazz)" , "prayer?" , "Friar" , "Religious brother" .)
