Translation of "Gazes" in Spanish

Mary sometimes sits still for hours and gazes at the sea.

A veces Mary se sienta durante horas y contempla el mar.

He who fights with monsters should look to it that he himself does not become a monster. And when you gaze long into an abyss the abyss also gazes into you.

El que lucha contra los monstruos tiene que procurar no convertirse en uno, ya que, cuando se mira durante demasiado tiempo a un abismo, el abismo también os observa.
