Lovely to see you posting so much! I was discussing the value of learning foreign languages with a French friend of mine who is also a teacher the other week and she remarked that learning a language is s'ouvrir à l'autre' (opening oneself up to the other). I think that there's something in the quote you posted in that art, like language, is so much about allowing for something outside of us to shape who we 'are', to allow for a Self which is ever-changing, fluid. The instability is scary, remaining open to it is hard work, but it's perhaps where our most beautiful encounters lie.
