Facing the years, a glass of wine, I hope the rest of my life will not worry about autumn.

The first half of this sentence means that life is short, years are like wine, and the first taste is sweet. If you experience more, you can taste the bitterness in wine.

The second half of the sentence means that even if life is short, we should enjoy the present. I hope that our future life will not be as miserable as autumn, but as full as summer.

Tagore's poem is to let life be beautiful like summer flowers and death like autumn leaves, similar to this sentence.
