"a heart full of love" is one of the les mis songs for which i find the translated lyrics so much better than the original french ones. in the french version, marius sings "my heart trembles" and cosette answers "as does mine", while the english version has marius singing "i am lost" and colette answering "i am found". instead of suggesting that cosette feels exactly same way marius does, like the french lyrics, the english lyrics emphasize, through the antithesis, how falling in love is a wildly different experience for each of them, but one that has an equally big impact on both their lives. later, in the french version, marius asks "is this a dream?" and cosette subtly rejects this idea by replying "no, this is real". while similar, the english lyrics don't have cosette dismissing marius' idea that he is dreaming, as she instead states that her own perception is different by answering his question of "do i dream?" by singing "i'm awake". falling in love is clarity and security to cosette and confusion and bewilderment to marius, and one perspective does not invalidate the other. the english lyrics fit the story of les mis so well because they highlight the idea that each person can experience love differently, and that there isn't one right way to love another human being.
