(a2a) There are several strategies which I would use: I suggest you learn all of them so that you can choose which is most appropriate when the need arises. You can:
Form a protective barrier around yourself;
Bind the spirit within something which acts as a “spirit trap”;
Go “invisible” – so that they completely ignore you;
Command their respect by invoking a superior power which they recognise;
Call upon a Spirit guide to protect you and deal with them on your behalf;
Ask them to leave of their own accord;
Forcibly banish them if they don’t leave peacefully.
You could try to burn them, but if you did succeed, it would probably only prove that you’re not on the astral plane at all, but rather still inside your mind.
Always try to find out why the spirit is behaving the way it is, before you get heavy-handed. I did hear about one incident where some witches claimed they were attacked by an evil entity – except that it turned out they had trespassed on a sacred site, and the entity was a perfectly reasonable guardian spirit just doing its job. The correct approach would have been for the witches to withdraw from the confrontation themselves.
But by far the best advice I could give is to prepare for astral projection by practicing this lot whilst you are still in your physical body. All of these strategies have their analogue in ceremonial magic, for example by calling upon angels or upon your Holy Guardian Angel, or assuming god-forms, or using rituals such as the lesser banishing ritual of the pentagram, etc. Practice them now so that you can deploy them at will when you are out of the body.
And always set your intention for what you want to do with your astral projection, and keep this firmly in your mind, before you leave the body: this will make sure you don’t turn up somewhere random and get surprised by something unpleasant.
