In the first quatrain the author turns to his beloved, to which he points out that the author is aging. Comparison, in fact, his body to the tree that sheds its leaves. He loses his hair with an aging process similar to that of yellow leaves that were once green. And as the branches of the tree that are shaking the cold winds of winter imminent, his limbs tremble at the change of time. Even his talk gets old and tired, it's not like the singing of the birds that once they felt.

In the second quatrain, the late fall from the tree is passed to the process that suffers the day with the passing of the hours. He is at sunset, when the sun sets in the west. As the sun sinks slowly on the horizon as night falls and brings sleep to the normal activities of the day. For him who speaks, and that is the last days of its existence, the night that shut down not only his life but also take away sleep, which is similar to it. He will not even sleep because the dark night stole his life.

In the third quatrain, the poet introduces yet a new metaphor comparing his life, near the end, to that of a fire that is dying out, a time that fire lit, now with the old is dying out.

Yet, all is not in vain. In the final part of his beloved offers her love and that love is stronger, although in the end. Even knowing that the approaching death will separate them forever, the dark night invites lovers to take care of those you love and be together because the time is now coming to end.
