LBRP ritual is a good shielding exercise (if you dont know what this is then do some research). Shielding requires regular practise and work though, like every day for half a year or so. I dont have the energy, too lazy! Once you are proficient at this you can expand the principles and adjust for other circumstances eg objects....
Having been beaten up by several people on these boards I'll warily answer.
Shielding is up to you. To effectively shield you have to know who you are. I mean spiritually. If you just in it becasue OOBE is cool, then, well go with the self shielding. Just picture a energy barrier around you (star trek style). It can be reflective, or sticky or like a brick wall. MAke it vibrate at a high frequency,a nd picture it full of the white light of goodness.
Now if you really know who you are, then you can go with physcial shields (devices marked and imbued with energy). There are many many ways to shield, and a lot of it comes down to how open you are about what you practice (as in are you hiding what you are doing from a parent or spouse?).
Ive been to spiritual healing a few times, the first time I went I explained how I'd suffered an attack. They told me that a simple way is to imagine yourself wrapped up in a big purple robe, pulling the hood over your head and tying it. Also imagine purple light/energy spiraling around your body from head to toe.

I just surround myself in the Divine White Light several times a day and especially when attempting to project, and sometimes for double protection, when I feel it is necessary, I imagine I am surrounded by a solid mirror facing away from me.
I think whatever makes you feel comfortable and you believe will work, will do just fine.[:D]

i create myself armor from my energy. its a hard technique, and im not sure how to explain it. but if anyone needs some, i would be happy to help you out.
How do you shield yourself, objects, and rooms?
