However tense, meditation can help with it (7)
I believe the answer is:
thought
'meditation can help with it' is the definition.
(meditate can mean to think or ponder)
'however tense' is the wordplay.
'however' becomes 'though' (synonyms).
'tense' becomes 't' (abbreviation used in many dictionaries).
'though'+'t'='THOUGHT'
(Other definitions for thought that I've seen before include "Reflection" , "Deliberated" , "Idea coming to mind" , "Content of cognition" , "just a trifle" .)
