The thing that will guide your blazing fire 
to becoming an even hotter flame...
ما سيقود نارك المتّقدة كي تصبح شعلةً أشدّ سخونةً حتّى
Das lodernde Feuer führt dich zu weit heißeren
Flammen und dem, der dir den Weg weisen wird.
El fuego ardiente lleva
a la llama apasionada y tu destino.
El fuego ardiente lleva
a la llama apasionada y tu destino.
Le chemin qui mène aux flammes
passe par la différenciation.
Ciò che alimenterà la tua fiamma
affinché arda ancora di più...
O fogo que queima vai te guiar 
a um local ainda mais ardente.
