Wow. Like to charge objects. But never tried. You people sound interesting. Have to try it sometime. Just need a starting point.  

I don't know about the whole gist of the question lol but I'll try
In my expierence I charge the "Whole" package into something.  Picture, color, feeling, etc.  Because In my expierence not everyone can pull all of it, the people I've tried with are usually limited to pulling it from only one sense.  ex. I charged a lighter with a spot up north where I use to camp at sunset.  I felt calm, at ease.  Nostalgia.  One friend pulled off the calmness, while another pulled a sunset.  Everyone is different, and so I tried to do something that all could use

As for changing the nature of something regardless of its surroundings...I guess I've never really tried that.  I have noticed that one can manipulate flames (ie candles and such) But I have never tried to charge a warm object to stay that way in the freezer.  Interesting, and worth a try  I do know that the lighter I used to charge still works, 7 years later LOL  It seems to have a charge to keep it up, regardless of how much fuel it has.  I have never refilled it, and used it quite often.  So I suppose in all sense it is possible to "Change" something

Hi  When I first started it was quite fun.  I would take something that holds something else, maybe a personal thing, but I believed that it was there to hold stuff lol For example, I first started with a pen or lighter.  A pen was made to hold ink, a lighter held lighter fluid.  Both were made to hold things lol

I would sit there holding it in my hand that pushed energy, close my eyes and imagine what I wanted to put into it.  The picture, feeling, colors, etc.  Then I would draw energy from the universe and transform it into that and push it into the object.  From there I would give it to other people and see what they could come up with

Hope you have luck with it

So how do you draw energy? By thinking it? Holding hands up?

I was told that the universe has an unlimited amount of energy, and that everything in turn is connected to it.  I visualize energy coming from all around me, the earth, trees, the universe, etc.  and see and feel it coming to me.  Sometimes I raise my hands at my sides when it starts to swirl around me, but often I just visualize it coming to me from all around me.  

I have been told by others that when they do it, they "Hug" or "Thank" the universe.  I in turn, alter some of that energy with love and send it back
