A very good poem overall
maybe something else than "infinite". It is superlative of superlatives so early into the poem.
"a light" as opposed to "my light" puts admiring distance between speaker and the object. Which, is probably your intent but maybe use another word that makes them more special. Not just a light among others, but 'the' light or something
"wise" does not really go into the theme I think, which in all other points of the poem is about outward appearance or sensory experience (hearing their laughter)
