Think of remarkable meat diet (8)
I believe the answer is:
meditate
'think' is the definition.
(meditating is a kind of thinking)
'remarkable meat diet' is the wordplay.
'remarkable' indicates anagramming the letters.
'meat'+'diet'='meatdiet'
'meatdiet' is an anagram of 'MEDITATE'.
'of' acts as a link.
(Other definitions for meditate that I've seen before include "Think contemplatively" , "Engage in contemplation" , "brood" , "Think to relax one's mind" , "Cogitate" .)
