Look around you. Wherever you live, whatever circle of society you are part of, you will notice that the vast majority of people live in the world without. Those who are more enlightened, however, are intensely involved with the world within. They realize—as you will, too—that the world within creates the world without.

This question is too basic; it can be definitively and permanently answered by a single link to a standard internet reference source designed specifically to find that type of information. See the FAQ for guidance on how to improve it.
I can see two interpretations of the quote depending on which meaning of "without" is intended.
The second interpretation seems less likely, unless this comes from something such as a mystic's journal.
EDIT: @StoneyB is right on. Stylistically, using "without" to mean "outside" and contrast with within is an older usage. It's found in older works and can make a modern work sound older.
Given the added context, I interpret the quote to mean that "most people are focused on the evidence or consequences of a "good" life (a.k.a world without) but not the real means to get there". The sentiment is akin to saying most people watch late-night infomercials about AB-Blasters. Fewer people hit the gym long enough to actually get those toned abs.
Note: This is a General Reference question, easily answered by any dictionary worthy of the name.
The full quote is:
Here, the words within and without are being used as modifiers following the nouns they modify and respectively meaning inside and outside.
So “the world within” simply means “the inside world”, and “the world without” simply means “the outside world”.
A dictionary would have explained this sense of without. The OED gives this use as the first of all of them for without. Here is a sampling of relevant senses:
