Hi, please use the tutorial @JezebelleMoon gave and look in this thread. I’m pointing to my journal that tells you how to charge a sigil and do banishing.
Banishing can be as simple as…
Opening a ritual: ‘I only invite the spirits that I work with in this ritual’
Closing: ‘If another energy or negative energy came through during this ritual then you need to depart immediately’.
And in my journal I describe the LBPR, it’s even guided so you can use it once in a while.
But the opening and closing statement you can use in every ritual.
The circle can be drawn around you with chalk (but it isn’t necessary). If you do that, it sets the intend. But it also can be done in your head. Image a white (white light) circle of protection around you. Meditate on it.
You can make it as complex as you want it, or make it as easy as you want it. You are the Magician you are the Master, you set the intend, it’s all about intent. Not about expensive tools.
