Aura / rays?

[BrownEye]

I used the technique here: http://www.thiaoouba.com/aura_eye_exercise.htm

It builds your perhipheral vision, which is what sees the aura.
I don't see them brilliantly, since that's not my gift.

It is just awkward for me to be staring at someone to see the aura build. But I've walked at dusk and the white rocks appear to be glowing. So I found it's easier to see when it's not too bright.

That's where I learned from also LoL. Try using a navy blue, dark blue stone to focus on. Once I got it down, it is possible to see it glowing even in darkness. Dark blue will put off a yellow glow.
