What are the lyrics to Poland’s national anthem, and how does it translate into English?

Katrina on Instagram: "The body speaks in waves, a silent rhythm of strength and surrender, its language flowing through muscles, through bones, through breath. To be fluid is to be free to let the currents of movement carry you without resistance, to let stillness echo its song in the pauses between motion. Here, in the dance of grace, we find ourselves whole, unfolding, expanding, and alive in the spaces where effort dissolves into ease. #yogaflow #yogainspiration"
