This is a mixture of a sort of magic that you control with your "imagination." there are also symbols you can depict with your body to make it easier for your "energies" to flow, of course.
If you were to observe that you have learned how 'planets' work, in your imagination, you will also understand that you can conjure effects with your mind interacting with the universe and the energies around it. by painting a picture, you can put your energies into it to paint with energy, of course. this would be where you need to also paint with your hands and feet, where you will use your songs to write syllables into the world around you to encase and edit the paintings, with sonic energy, of course.
~ So, the focus is on sonic energy, mental energy and semantics or body language, of course.
If you were to observe that you can imagine a great deal of things, then you could imagine something that the world around you does not understand. if you were to focus on something that exists, then there is something you know about it, and there is information to work with. if you were to study something, like watch it take place with your eyes and ears, you could feel a certain way when this happens, tensing up and drawing back - a cupped backward defensive motion with your hands, like when you draw your child away from this event - or even something you launch yourself at, like when you are in a bad mood and hit your pals, yes? so, there are natural semantic components too!
With these body language actions in mind, you could place energy into them by focusing your energy into your hands and body, and then focusing on them being sensitized. this would be where you need only flex and relax in certain areas to show how far it will be - if you were to tense up your forearms, you will find it is at moderate range, if close by, your hands, if far away, your biceps, yes? this will be where you focus your energies inside the 'painting' too. the legs will show where they go in positive balanced or negative energy, the intent of 'the power,' of course.
Then, there is the actual 'painting.' this could be a moving picture, where you encircle yourself with the image, to focus on yourself, put holes in it, to show that powers will come from you to escape, and of course hazy to depict a power that will be everywhere, to put it in terms that are easy to understand. if your painting is under or above you too, then you will tap more positive, indifferent or negative energy into or through you, with hazy being attracting, dense being deflecting and so forth.
Lastly, there is 'sound.' the sounds you make are also 'magical' as it will show how you will affect the power with those said 'energies.' of course, the sounds you make follow a science, where the understanding of the words you use will affect your power like a phonetic language, something i have written intensively about in the past. for example, "ba" is to strike or affect or propel downwards, or, "ka" is to do it like a hay maker swinging punch, okay? if you want to be more passive, which i bet is not the case, as i bet you want to make energy manifest, you should think of baby noises, of course.
These are the fundamental rules of psionics, as far as i have discovered so far.
