first of all...there is no such thing as a psionic 'mage'... psionics is a science, not magic...
secondly yes. believe it or not there are forums which discuss these ideas. it all comes down to your mind's force of willpower. a novice psion could struggle with spinning the psi-wheel, both because he is young to the skill and mentally untrained, and because most beginners are skeptics. But a psionic adept would be more than capable of, say, moving objects with his mind or being able to tell how many people are in a submarine that is trapped under a mass of pack ice. Psionics is mostly about energy, because energy is the vehicle for all activity. Healing through psionics is a very popular and common discussion, and is practiced by many people...sadly, human nature effects even psionics, and psychic healers are few and far between.....people who would use this power for foul purposes-though a rather small number, due to psionics being a very new practice- still outnumber those who would use it for good...
Psionics is powered completely by belief. You must believe in what you are doing for any successful outcome to take place. After this comes willpower, the influence of your mind upon the things around you. Belief encourages you to try, which helps build willpower to succeed. Then you have energy, which is molded by the will of the mind to become the physical interpretation of what the mind's eye sees happening, which is in turn the successful outcome.
