There are no real divisions between the perceiver and the thing seemingly perceived. In many ways the thing perceived is an extension of the perceiver. This may seem strange, but all acts are mental, or if you prefer, psychic acts. This is an extremely simple explanation; but the thought creates the reality. Then the creator of the thought perceives the object, and he does not understand the connection between him and this seemingly separate thing.
This characteristic of materializing thoughts and emotions into physical realities is an attribute of the soul. Now in your reality, these thoughts are made physical. In other realities, they may be "constructed" in an entirely different fashion. So your soul, that which you are, constructs your physical daily reality for you from the nature of your thoughts and expectations.
You can readily see, therefore, how important your subjective feelings really are. This knowledge -- that your universe is idea construction -- can immediately give you clues that enable you to change your environment and circumstances beneficially. When you do not understand the nature of the soul, and do not realize that your thoughts and feelings form physical reality, then you feel powerless to change it.
