Do spirits exist in the world?

A grain of sand in a whole vast desert of comparative spiritual stature is like your school books. 

You were obliged to start at the beginning. 

A peep at the end of them would reveal things far beyond your then capabilities and so would convey no meaning whatever.

Spirits are in no different case here as regards innumerable problems or questions. So they jog along and find they are none the worse off for not knowing the answers.

Everything fits into its proper place in these lands and none would be handicapped in their progression by lack of knowledge.

The knowledge will be there at the right moment.

In the meantime, there is no harm in their having as many discussions as they like among themselves—

This is a sensible world.

One soon shakes off the physical characteristics that belong to the earthly side of life and puts on the spirit world personality. Thereafter, longevity makes no difference.
