We are in this physical world, but we are not from this world.
It is important to understand that there is an evolution of Souls going on through the earthly experience, but also a development for every individual Soul. This is how the passage into higher and higher dimensions can be explained in simple terms.
Rene Descartes, Contributor Waking Times
There are many immature Souls on planet Earth, and also many misguided Souls. Other Souls do not possess the best intentions, or are simply controlled by beings without a body, whose intentions and evolutionary process are not commendable. Many dope addicts and alcoholics have this unfavorable trait as do many selfish and greedy people. Few humans, because of their inclinations or because of their immaturity allow unknowingly those beings to manipulate them from time to time. Those being I am referring to, are not yet developed as a Soul, nor a Higher Self or higher conscious awareness, only the mortal and limited intellect.
