Tea chest turned up in yoga centre (6)
I believe the answer is:
chakra
'yoga centre' is the definition.
The definition suggests a singular noun which matches the answer.
'tea chest turned up' is the wordplay.
'tea' becomes 'cha' (cha is a type of tea).
'chest' becomes 'ark' (historical term for a chest).
'turned up' shows that the letters should be reversed in order.
'ark' reversed gives 'kra'.
'cha'+'kra'='CHAKRA'
'in' is the link.
Can you help me to learn more?
(Other definitions for chakra that I've seen before include "In Indian thought, one of the centres of spiritual power in the body" , "One of seven bodily centres of spiritual power" , "One of seven centres of spiritual power in the human body" , "A centre of spiritual power in the body (yoga)" .)
