What does Tagore's poem "Paper Boats" tell us about the ways of children?

Tagore's poem "Paper Boats" tells us that the ways of children are highly imaginative. In this poem, the child speaker plays with his paper boats. He envisions putting pieces of paper with his name and village written on them in these fragile vessels and setting the boats to sail far away. He hopes that the boats will land in "strange places" and that the people there will become aware of who he is.
The speaker also loads his boats with flowers and sets them off, hoping they will come safely to land. He imagines as well that a friend in the sky sends down the clouds to race with his boats. He also dreams that fairies sail his boats at night.
In addition to showing how imaginative children are, the poem shows how they long for connection with other people and places. Children anthropomorphize nature—the child thinks the clouds are racing his boats—and they believe in the supernatural. All of this blends together in the child's imagination as one harmonious whole.
This magical and optimistic sensibility, open to all possibility, lends this poem its tone of lightness and joy.
