I found this definition at https://www.merriam-webster.com/dictionary/ardent

i found this word in A hunger artist “and the joy of life streamed with such ardent passion from his throat that for the onlookers it was not easy to stand the shock of it.”

the definition really helps because it shows the warmth of support and joy that he got. He shows how shocked he way and how amazing it was and how he couldn’t stand the shock of it. The word gives it more feel.
