What does this below rebus puzzle mean?

These types of puzzles are known as charades. What you have to do is to find two words that are referred to in the first stanza and the second stanza and put them together to form the third word in the third stanza.

My second is my first of space
Defining people's present place.

My whole describes a lack of site -
A place without length, breadth, or height.
