Locard Exchange Principle

From Wikipedia:
The Locard exchange principle, also known as Locard’s theory, was postulated by 20th century forensic scientist Edmond Locard.

Locard was the director of the very first crime laboratory in existence, located in Lyon, France. Locard’s exchange principle states that “with contact between two items, there will be an exchange.” (Thornton 1997)

Essentially Locard’s principle is applied to crime scenes in which the perpetrator(s) of a crime comes into contact with the scene, so he will both bring something into the scene and leave with something from the scene. Every contact leaves a trace.

“Wherever he steps, whatever he touches, whatever he leaves, even unconsciously, will serve as a silent witness against him. Not only his fingerprints or his footprints, but his hair, the fibers from his clothes, the glass he breaks, the tool mark he leaves, the paint he scratches, the blood or semen he deposits or collects. All of these and more, bear mute witness against him. This is evidence that does not forget. It is not confused by the excitement of the moment. It is not absent because human witnesses are. It is factual evidence. Physical evidence cannot be wrong, it cannot perjure itself, it cannot be wholly absent. Only human failure to find it, study and understand it, can diminish its value.” -Professor Edmond Locard

So is it the same with social exchange? Intellectual exchange? With every contact, does one person leave something of himself/herself and take away something from the other?

Sometimes I see something I wish I had never seen; I wish never to think about it again, but it is saved indeliably to some brain cells. I can forbid it, I can tell myself not to think about it, with some long term success, but it never truly goes away, I am just refusing to give it any time. Nonetheless, the mere contact with it, the sight, or sound, has changed me in small ways forever.

Are the laws of the spiritual world in any way analogous to the laws of the material world?
