There is no such thing as immaterial matter. All spirit is matter, but it is more fine or pure, and can only be discerned by purer eyes.—Doctrine and Covenants 131:7
If the Lord would permit it, and it was His will that it should be done, you could see the spirits that have departed from this world, as plainly as you now see bodies with your natural eyes. Where is the spirit world? It is right here. —Brigham Young
