I used the shield with ketric light. After cleaning space with the lesser banishing pentagram, i visualise the light wrapping around me, and tell my requests (to the light). I asked that negative things can't enter, and negative things in me are thrown away from me. I also tell to diseapear at the end of the afternoon (i said an accurate hour, like 10 pm). Well, during the day, i really felt the shield. It worked. But... at 10, suddenly a lot of negative thoughts "jumped" at me at the same time... and i was in peace just before. Those thoughts were some i feel sometimes during the day. So, two points : - it worked well, i could feel the result. - A VERY important thing to me : what you ask to the light is taken at the letter. I think negative thoughts was around me but couldn't enter, and when the shield diseapeared, they entered. So, the point is : pay attention to the instruction you give to the light. If one day i want to recreate one, i think i would ask it to destroy negative thoughts which come at me, or throw them FAR away (and not simply say don't let them come in me). I give you my advice : try to create a shield, but for only a day. Look at the result. Analyse. If all worked well, MAYBE it could be possible to wear it a longer time. It was just MY opinion. If you have question, i'll be pleased to answer them.
