Here’s an interesting quote by Charles Haanel:

“The Universal Mind is the life principle of every atom which is in existence; every atom is continually striving to manifest more life; all are intelligent, and all are seeking to carry out the purpose for which they were created.

A majority of mankind lives in the world without; few have found the world within, and yet it is the world within that makes the world without; it is therefore creative and everything which you find in your world without has been created by you in the world within.

You will at once see that this is a radically new and different idea; most men try to change effects by working with effects. They fail to see that this is simply changing one form of distress for another. To remove discord, we must remove the cause, and this cause can be found only in the world within.

All growth is from within. This is evident in all nature. Every plant, every animal, every human being is a living testimony to this great law, and the error of the ages is in looking for strength or power from without.

The world within is the Universal fountain of supply, and the world without is the outlet to the stream. Our ability to receive depends upon our recognition of this Universal Fountain, this Infinite Energy of which each individual is an outlet, and so is one with every other individual.”
