Hoja en blanco literally translates to "blank page". It's a poignant and evocative phrase that carries significant emotional weight in the song.
In the lyrics, the singer receives a letter from a past love, only to find it's a "hoja en blanco." This symbolizes the complete lack of information or connection they've had since their separation, highlighting the pain of not knowing what became of the person they once loved. It's a powerful metaphor for lost communication and unresolved feelings.
"Hoja En Blanco" ("Blank Page") is about the long ache after someone leaves without any real explanation.
The singer describes a love she couldn't forget, then a farewell she compares to a train pulling away with someone's whole life on board. Years pass. She goes back to her hometown and learns from neighbors that he has already married someone else, and she can't bring herself to say anything back.
The chorus turns to the moon as a witness: it saw both of them in love once, and it still sees that she hasn't let go, even while she tells him to fly toward his own future.
The saddest image comes near the end: a letter finally arrives from him, and when she opens it, the page is blank. After everything, she never gets the answer she wanted. She's left loving someone who gave her no explanation at all, only a lifetime of guessing.
