Hi Courleciel,
please find here (http://bricksafe.com...charly/test.pov) a complete povray-file (3.7) which I set up especially for you.
Basic scene:
Scene with enlighted brick, inner aura and outer aura:
Not sure, if this is the effect you wish to achieve. However, what you see is more or less the result of copying the scene file out of the POV-Ray Tuto and applying it to the basic scene above.
Now it's up to you to tweak it to suit your needs. I would highly appreciate to see the results of your project here.
…. and may the force be with you.
regards
