The Sacred Fire
Diverse, progress, change
Captain REX said "Gandalf was not human. He was a Maiar. So put me down as a Maiar; if not, then the average man will do. It's through this race that Middle Earth is saved, after all."
Not entirely. Without the influence of certain Maiar they would not have the guidance and wisdom to endure some of the events that they did.
It is a collaborative effort of all (good-willed) races that they constantly triumphed over evil. That is of course one of the messages of LOTR.
NickLOTR said "I want to be an Istari Wizard. A White Istari Wizard. This way i could be inpervious, and also go to the undying lands.
i remember reading that Gandalf was called an "Istari" idk what all these other words mean.. like maiar.... I read he's an Istari wizard sent to earth by the Valor."
The Istari were not impervious. Not physically anyway! I mean for crying out loud they were old men, they aren't exactly bodybuilders, as that wasn't fitting for their purpose. They could die quite easily under the cloak of an old man (Gandalf and Saruman prove this, Gandalf's death was amazing as he endured so much before dying). Their spirit is the immortal part of them. They were only as physically strong as your grandparents my friends!
Gandalf, like other immortal beings, had many classes and orders. He didn't just belong to one only. He was a Maiar, an Ainur and an Istari.
