Most spiritual beings dont manifest on a physical level. The only way to see them is through astral projection. I have however come across a technique that i refer to as "astral eyes". This is where you convert just your eyes to there astral form. It can also be done with other parts of your body for instance, your hands. It makes energy manipulation alot easier. Keep in mind that to everyone else you will not change in appearance. If you can astral project and want to learn this method please message me.
One needs to open your third eye, one needs to work on seeing energy first, once you can see it you can work from that point forward, seeing any beings means your mind needs to be able to comprehend them without unravveling, thus if you are not ready to see beings from a energy plane then you won't, trying to force it via rituals or summonings will only be bad for you in the long run.
learn to feel energy clearly, from there percieving it on a visual level is much easier.
