I believe the answer is:

<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">priest of the east</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for lama that I've seen before include "Dalai . . . ., chief priest and once ruler of Tibet" , "A Tibetan Buddhist priest or monk" , "devout Buddhist" , "Tibetan spiritual leader" , "A Buddhist priest in Tibet (4)" .)
