Congratulations on this. I always like your work, though, I am often stunned by the brilliance to know how to comment. A simple, well done, never seems suffice.
I like the phrasing and the metaphors. The tongue is the writers voice, right? Harvesting the inspirational words from a place far away, away from view. I like the imagery of the crescent moon being turned to follow the contours of lips, like a smile, perhaps? The 'unplucking' could be the deciphering passages of text or poetry? This text, this voice sounds wounded and your efforts (earnestly toil) is gentle and nurturing, using skill and love to grow what feels right and familiar.
