Thought from Mao's first volume receiving cheers (10)
I believe the answer is:
meditation
'thought' is the definition.
(meditation is a kind of thought)
'mao's first volume receiving cheers' is the wordplay.
I cannot really understand how this works, but
'first' could be 'i' (I in Roman numerals eg Elizabeth I) and 'i' is found within the answer.
'cheers' could be 'ta' (I've seen this in other clues) and 'ta' is found in the answer.
This may be the basis of clue (or it may be nonsense).
'from' acts as a link.
Can you help me to learn more?
(Other definitions for meditation that I've seen before include "Deep relaxing thought" , "Contemplation" , "serious thought" , "reflection" .)
