This currently seems to be the most popular method amongst Psionic practitioners.
It is often useful to create an abstract image of some kind representing or symbolizing the result you seek (your goal from exercise #3 might be a good idea here). You can embed certain symbols into the representative abstract image which help to relay your intent (what you want to happen) or you will. Focus of some kind on the abstract image you have created is known to be useful. After this focus, choosing to bring your attention elsewhere is also known to be effective. Many practitioners agree that forgetting - literally - what your focus was on, while choosing a different activity to work on, is effective. We will leave the details of how to do these things up to the student.
This method seems to be particularly effective in telekinetic and telepathic applications. Create a symbol which represents what you want to do. If you are trying to do telekinesis, an effective focus here might be to create a symbol which represents “move (object here)”. Create another symbol which means “link me with the object (or person)”. Physical contact is effective here. Photographic links might also be effective. You might even wish to photograph yourself with the object. If you wish, you can charge the photograph with your intent. You can also try creating many links, each representing a different scenario & link them together mentally. This is a field of experimentation.
Think of something you wish to occur. Mentally visualize and will yourself full of “energy”. Now, confidently state your intent that your wish is being fulfilled. Visualize and will the energy in yourself to form into a ball shape that represents the state of your wish being fulfilled. Finally, release this ball into the void with the belief that your wish will definitely be fulfilled. Like always, practice this for awhile (a week or more) and note your results in your journal.
What you have created in this exercise is generally referred to as a “construct” in our community. There are many articles and courses which can teach you how to create energy balls of various types.
