Charles Haanel, and many similar authors of metaphysics, often talk about the world within and the world without. I question those terms for what usually refer to the mental world and the physical world. 

Is the world within really within? If so, then what is the world within, within?

Is it for certain that the so called worlds within, and without, occupy those complementary spaces? Maybe they don't even exist in the same dimensional space. 

Within and without seem to imply containers of space. They imply that the world within is contained by the world without. I'm not sure this is an accurate way of looking at it.
