2. Visualize a sphere of white light encasing the ghost like an impenetrable bubble, then either visualize the bubble, ghost and all, floating into the light or imagine angels/guides moving it into the light.
You can, of course, play with this a bit. It doesn't have to be a bubble. It could be a bell jar or anything else that traps the spirit inside and can be moved by you (with or without the help of others) either outside of your room/house or all the way into the light. Personally, I don't see the point much of just putting them outside. Why not get rid of them altogether by having them go to the light? Then they can begin their life-review, re-education, and spiritual development process.
3. You can surround and encase the being with love, then bundle them up in white light and hand them over to angels/guides to be transported into the light.
When I'm dealing with something really nasty that may be powerful, I use quite a bit deeper trance state. Then I focus on sending the entity love. Pure, deep, unconditional love that flows around them like a thick pink blanket. Truly evil beings hate love. They enjoy fear, rage, and anger. In fact just about any negative emotion pleases them. But love is something they simply can't deal with. They shrink away from it. But in this case, they can't, because I have them utterly surrounded by that energy. Then I encase the entire mass in a sphere of white light, making sure to wrap them up tight like a mummy, and hand them over to angels/guides to bear away to the light for re- education. I can't stress enough that if you have any fear you can't do this technique. Your feelings of love for that lost soul must be deep and sincere. But when you can do that, it's an incredibly powerful technique.
Why move spirits on? There are a couple reasons. If you have entities that are saying bad things to you or getting you into trouble you DON'T want to let them stay. Likewise, if you believe in reincarnation, allowing a ghost to remain stuck is really not in its best interest because it keeps them from progressing. So, even if you like their company, I'd recommend encouraging them to finish their transitions. Remember, they can always choose to come back and visit you again from the light. They just won't be earth-bound if they do so.
One last thing. If the spirits are guides you won't be able to get rid of them. This is because they are supposed to be with you. Of course, you should be able to tell the difference between them and a ghost so that you won't want to try to move them to the light. It should be clear from your interactions with spirit guides that they have your best interests at heart and are encouraging you in positive, helpful ways.
After the Spirit Has Been Moved On
Once you've finished moving the entity on to the light you still aren't done. It's time for a bit of cleanup. After all, you don't want to take chances on it or a similar spirit coming back, and some of that energy may hang around for awhile afterwards even though the spirit itself is gone. I think of this cleanup work as involving three stages:
1. Shielding the person/location that was being haunted. The simplest way of doing this is to visualize white light surrounding the person/place that you evicted the spirit from. This is no different from the ordinary shielding you
