Summarize the following poem:

Because I have seen Bengal’s face I will seek no more;

The world has not anything more beautiful to show me.

Waking up in darkness, gazing at the fig-tree, I behold

Dawn’s swallows roosting under huge umbrella–like leaves. I look around me

And discover a leafy dome-Jam, Kanthal,

Bat, Hijol and Aswatha trees–

All in a hush, shadowing clumps of cactus and zedoary bushes.

When long, long ago, Chand came in his honeycombed boat

To a blue Hijol, Bat and Tamal shade near the Champa, he too sighted

Bengal’s incomparable beauty. One day, alas. In the Ganguri,

on a raft, as the waning moon sank on the river’s sandbanks.

Blow, blow, thou winter wind,

Thou art not so unkind

As man's ingratitude;

Thy tooth is not so keen,

Because thou art not seen,

Although thy breath be rude.

Heigh-ho! sing heigh-ho! unto the green holly, Most friendship is feigning, most loving mere folly: Then heigh-ho, the holly!

This life is most jolly.

Freeze, freeze, thou bitter sky,

That dost bite so nigh

As benefits forgot:

Though thou the waters warp,

Thy sting is not so sharp

As friend remembered not.

Heigh-ho! sing heigh-ho! unto the green holly...

I love to rise in a summer morn,

When the birds sing on every tree;

The distant huntsman winds his horn,

And the skylark sings with me:

O what sweet company!

But to go to school in a summer morn,

O it drives all joy away!

Under a cruel eye outworn,

The little ones spend the day

In sighing and dismay.

Ah then at times I drooping sit,

And spend many an anxious hour;

Nor in my book can I take delight,

Nor sit in learning's bower,

Worn through with the dreary shower.

How can a bird that is born for joy

Sit in a cage and sing?

How can a child, when fears annoy,

But droop his tender wing,

And forget his youthful spring!
