Tuffy. It is mentioned on the JoS that when one has empowered ones Aura only has to use their Aura to do magick, along with their visualization/intent. I've known this consciously for a few years as the Gods have given me the information, as far as the engraving things like Runes upon the Soul (well my approach is a little different). You can not only do magick through the aura, but you can also teach via the giving of energy. So if you care enough for him, you would work on yourself, and then do rituals to send blessings to him to change his aura/mind. A sort of Telepathic Magick (do not ask me, but you may find this out simply by reading JoS and combining certain techniques). Then, I am assuming you do Visitations, phone calls, or letters to him so you can talk to him so that it is something he consciously understands and can work with you on.
