Gandalf's body was mortal, subject to the physical rules of Middle Earth, but his spirit was immortal, as seen when he died as Gandalf the Grey and resurrected as Gandalf the White.
Тело Гэндальфа смертно, оно следует законам жизни в Средиземье, но дух его бессмертен. Умирая как Гэндальф Серый он возрождается как Гэндальф Белый.
