"Sleep-stealer"

Who stole sleep from baby's eyes? I must know.
Clasping her pitcher to her waist mother went to fetch
water from the village near by.

It was noon. The children's playtime was over;
the ducks in the pond were silent.
The shepherd boy lay asleep under the shadow of the
banyan tree.
The crane stood grave and still in the swamp near the
mango grove.
In the meanwhile the sleep-stealer came and, snatching
sleep from the baby's eyes, flew away.
When mother came back she found baby travelling the
room over on all fours.

Who stole sleep from our baby's eyes? I must know.
I must find her and chain her up.
I must look into the dark cave, where , through
boulders and scowling stones, trickles in a tiny stream.

I must search in the drowsy shade of the bakula grove,
where pigeons coo in their corner, and fairies'
anklets tinkle in the stillness of starry nights.

In the evening I will peep into the whispering silence
of the bamboo forest, where fireflies squander their
light, and will ask every creature I meet, "Can
anybody tell me where the Sleep-stealer lives?"

Who stole the sleep from baby's eyes? I must know.
Shouldn't I give her a good lesson if I could only
catch her!

I would raid her nest and see where she hoards
all her stolen sleep.
I would plunder it all, and carry it home.
I would bind her two wings securely, set her on the
bank of the river, and then let her play at
fishing with a reed among the rushes and water lillies.

When the marketing is over in the evening, and the village
children sit in their mothers' laps, then the
night birds will mockingly din her ears with:
"Whose sleep will you steal now?"

— Rabindranath Tagore

I think as Tagore's poems go , this one has a certain robustness in it's form and rhythm and I do think it reflects the unending quests in life.
The line that really stood out to me: "where fireflies squander their light"
To me this was very painful somehow - how meaningless some of our actions can be....
The poem as a whole - loved the descriptiveness - the beauty of the countryside - the detailing - I can visualise the pictures in my head.
What the whole poem itself means - I think I will wait for comments for others and round it up later!
