Here’s a related, interesting comment I recently encountered:
“A tzaddik is so captivated by the love of G-d that he attends to mundane matters almost casually, preoccupied, as he is, with far more exalted interests. During ordinary discussion his mind relates the subject at hand to G-d by natural transfer, like a lover whose every experience reminds him of his beloved.”
