you may say only kidding,but think of it another way,and you may be eating your own words...
are we just simply spirit,living in a physical shell ?
i read a book on reincarnation and "life between lives",it covered many personal accounts of regression where the individuals recalled specific points of their loved ones they had just left behind,in order to transmit energies to aid the grieving process....there were many cases stating the same or similar accounts,
one example is a man who just after his physical death,he didnt want to leave his grieving wife,untill he was content she was able to "sense" him and be uplifted.
Allthough it didnt go into great detail on what he "saw" her like...it did refer to him emitting energy through to her using a point on her body she was familiar with him touching when he was physically there,on this occasion he chose to manipulte a small spot next to her ear ..
i can only assume that if this was indeed possible he must have been able to distinguish bodily parts of her or anyone for that matter in order to do this.which makes me wonder if we dont actually look much different to spirit than we see one another physically.I guess the same can be said for physical touch too,how wld it be possible to embrace someone or comfort them,hold their hand etc if all they were seeing us as was a form of energy/light etc..
