Rayando comes from the verb rayar, which literally means "to scratch" or "to graze". It's a fascinating word choice for the song's iconic title, "Rayando el Sol" (Grazing the Sun).
In the song, this phrase is used poetically to describe staying up all night in despair, waiting until the first rays of dawn appear to "scratch" the horizon. It paints a powerful picture of sleepless nights and a desperate, endless longing for a lost love.
This is one of Maná's most famous rock anthems, and it's all about a love that feels completely impossible. The singer is in total agony over someone who doesn't return his feelings. The title itself, "Rayando el sol," means "scratching the sun." It's a powerful image for trying to do something you know you can't, like reaching out and touching the sun itself.
The whole song builds on this idea of an impossible task. The singer lays it out very clearly with the line, "Es más fácil llegar al sol, que a tu corazón" (It's easier to reach the sun than your heart). He's desperate, telling this person "No me has llamado, estoy desesperado" (You haven't called me, I'm desperate) and that the pain "me duele, me quema sin tu amor" (hurts me, burns me without your love). It's a classic, over-the-top declaration of heartbreak.
