One more thing... It just came to me you could do this exercise: Looka past the person who's aura you are lookin at. Literally if that person is 2 metres from you, look at the distance of 5 metres. While looking at teh person. At a ceratin point your vision will get stabilized to look further than the person and you start to see the aura. The best view is generally slightly off the focal point. And remember to breath;-)

That's what I do when I see auras. As far as I know ;-)))
