Atravesar means "to cross" or "to go through." While it can refer to physical movement, it often carries a deeper, more metaphorical sense of overcoming obstacles or enduring experiences.
In "Fuerte Pa Volar," the artist sings "Soy fuerte pa atravesar lo que va a pasar" (I am strong enough to go through what's going to happen). This highlights a theme of resilience and readiness to face life's challenges, making it an engaging word that speaks to inner strength.
