btw Gnosis is right and the link is gold, just substitute the third eye for another chakra or set of meridians. Work on it until you have a firm grasp on what you want to get done.
Look, I will share a personal ritual for everyone because I had these problems not too long ago. No one really helped me identufy what I was looking for I had to feel it for myself. It just helps to know what to look for when it happens, so you can cultivate energy a little better.
I evoked a lot of shit that seemed like it didnt work, but I wasnt tuning into the right state and when I was it was a stepping stone for personal experience as to the potential was this can manifest.
First spend a week paying attention to what you do. Seriously. Get your journal and map out your day. What time you wake up, to what you eat, how many times you masturbate, to how many times you blink. Write it down. Dont lie to yourself you will not grow as much. This can make a person aware of their subconsious attachments and what they generally gravitate to.
Figure out your habits and learn your chakras then associating these attachments to the prescribed chakra and work on the blockage from there. I printed a subtle body map from robert bruce’s astral dynamics and took a full body picture of myself and overlayed the energy map over the selfie. Created a chart and associated my attachments to what I knew of my chakras and became aware of what I was actually doing.
At this point if you come across a weakness, EA made a video about naming your enemy. You now have a name and a way to help clear that attachment. Watch his Youtube channel.
I made index cards and sigilized these blocks then used a black mirror to concentrate on it and confront the issue. Burn the sigil when you feel you need to move on.
I had a pile of Index cards made. Each time I burned one, I felt awesome. I treated it like it was medicine and anticipated the cure. Helped let go of attachments and cleared up some things for me.
I went through a lot of weird psychological shit. Think about it you just removed something from your body. Physical or not you will want to try to fill the void of that attachment and my become depressed or experience emotional disturbances. If you wrote down everything you now know why you are feeling that way and how to deal with it.
I also, implemented a healthy diet and workout program to help my body. Balance is key.
Basically if you can get into the proper states of mind (t/g sync) and write down your actions you will see why you are the way you are.
Doing stuff like this helped me is so many ways. Getting all of that out of the way will pave better ways for your evocations/divinations. You will ask better questions in evocations and see your divinations before you touch your tools.
