D&C 131

The Prophet Joseph Smith taught an important doctrine in his day -

"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;
8 We cannot see it; but when our bodies are purified we shall see that it is all matter."  (Doctrine and Covenants | Section 131:7 - 8)

I find it interesting that the emphasis is seeing spirit matter.  It does not necessarily mean that we cannot feel such.
