To help be properly safe from psychic attacks I would like to pass on a useful tip.
The first part is to make yourself an inner space ...a place inside you where with a little practice you can go and be quiet and meditate relax etc.
Think of a place you remember well and is special to you.
Once you have a picture of it in your minds eye ,explore it and look at every detail.
After you have done this for a while and are completely familiar with it, think of somewhere else.
Now go back to the first place you thought of (it should look pretty much the same) and Add a sitting place ..it should be something that was never there before, for instance a tree stump or a rock maybe even a log or a park bench if that is what you like.
Now explore that in the finest detail, touch it and feel it's texture, look at all the colourrs in it and make sure it is well stuck down where you put it.
now think about the other place again.
Once you have it clearly go back to the place with your sitting item in it.
Is it still there?
if not repeat the first exercise again.
If it is congratulations you have just made a place in the Astral that is yours and yours alone. The sitting place is now a link from your essence into the Astral that is your inner space.
Each time you want to go there think about sitting on your chosen item and with practice you wil go there reasonably easily.
if you want to -*test*-('") it try making it snow there or rain or both at once.Basically you can do anything you want in that space it's all about what your imagination can do with it.
Now the safety part.
Think about you inner space and talk to it .
Tell it that no one with any evil intention is to be allowed in to your space then tell it that no one with any evil intention is to be allowed to stay within your space. This will let friendly entities visit you.
Make some signs and place them around the edge of your inner space (you only need to think of this not actually do it) and you are done.
You are now safe from anyone entering your Aura and doing bad things.
You will still need to learn some shielding but this will keep out any and all wrong doers so that they can only work from outside.
If things get difficult it is a simple task to tell your space to not let anyone at all in. But it is really a last resort and not really neccessary once you get the hang of the above idea.
