See what "I" means?

The first person singular perspective. Your point of view. Who and what you are as expressed repeatedly by the unholy trinity....me, myself and I.

The thought process takes advantage of the inability of the egoic mechanism, (like a shock-absorber or better yet a "skim" operation in any financial enterprise....) to short-circuit the flow of energy and rather than allow your real self from expressing your real intent, it bleeds away the incipient energy and leaves you with only a pale aftertaste of your real essence.

As "normal" (read typical) as this function may be, it is not NATURAL. The nature of man is to induce and transmit his essence into this reality so that he can interact with the material plane. The thought process is a method whereby the circuitry of the mind is insulated from the full force of our energy until such time as we become able to transmit the vibratory quality of this force without unbalancing our very beings.

Not so much a straight-jacket as a life-jacket, thoughts are meant to be discarded as soon as you are out of the sea of doubt and able to continue your journey. Once you are aware of them, you can remove the encumbrances and gain the freedom that you need to succeed.
