Amordaza comes from the verb amordazar, which means to gag or muzzle someone. It's a strong and somewhat unusual word to find in a romantic song, making it particularly intriguing.
In the context of the lyrics, "Tu sed que me amordaza" (Your thirst that gags me), it's used metaphorically. It suggests that the intensity of the lover's desire or passion is so overwhelming that it silences or consumes the singer, leaving them breathless and unable to speak. This vivid imagery creates a powerful and memorable expression of deep passion.
David Bisbal describes falling into a lover's body as if it were a whole world to explore. He climbs, learns, and travels across her the way you'd cross new territory, calling her feet his starting point and the road ahead a long journey nobody else will ever see.
The song lingers on touch: hands, mouth, legs, the shared breath. Night becomes humidity, a sigh becomes a tear, and the two of them dissolve into each other until "the soul leaves the body." For him, this closeness is where love feels singular and honest, so he calls it the road to truth: not a place, but the feeling of being fully known by someone.
The floating, weightless imagery in the later verses (sheets, drifting, nothing weighing him down) captures how consuming that intimacy is. Nothing else matters once he's there.
