Enjoying the poem

[akbar]

Lightly, o lightly we bear her along.
She sways like a flower in the wind of our song;
She skims like a bird on the foam of a stream,
She floats like a laugh from the lips of a dream.
Gaily, o gaily we glide and we sing,
We bear her along like a pearl on a string.
Softly, o softly we bear her along
She hangs like a star in dew of our song;
She springs like a beam on the brow of the tide,
She falls like a tear from the eyes of a bride
Lightly, o lightly we glide and we sing,
we bear her along like a pearl on a string.
I found this poem in a magazine. No title and poet’s name in it. But I like the content even though I could not follow this completely.
Some questions are arising in my mind. I guess this is about palanquin bearers carry the bride. Flower, bird, laugh and pearl indicate the lightness of weight. But which words indicate the movements of palanquin. Are they lightly, softly, gaily, and glide or hangs, springs, and falls. Falls means getting down from palanquin? She floats like a laugh but in line 10 she falls like a tear. Why are laugh and tear used along with?
Give your opinion. I hope all of you like this poem.

Lightly, o lightly we bear her along.
She sways like a flower in the wind of our song;
She skims like a bird on the foam of a stream,
She floats like a laugh from the lips of a dream.
Gaily, o gaily we glide and we sing,
We bear her along like a pearl on a string.
Softly, o softly we bear her along
She hangs like a star in dew of our song;
She springs like a beam on the brow of the tide,
She falls like a tear from the eyes of a bride
Lightly, o lightly we glide and we sing,
we bear her along like a pearl on a string.

. . . which words indicate the movements of palanquin?

Sways, skims, floats, glide, bear, hangs, springs, and falls.

Falls means getting down from palanquin?

"She falls like a tear from the eyes of a bride". They are tears of joy, and tears fall in the shape of a tear-drop, which describes the shape of the paranquin, not her state of being.

She floats like a laugh but in line 10 she falls like a tear. Why are laugh and tear used along with?

The shape of her falls (i.e., hangs down) like the shape of a tear-drop.
