here's a good aura thing, first you feel your aura turn into light or golden light, golden light is recommended though, feel the gold light surround you like a cocoon or blanket of energy. you could also feel the golden light surround your body like a egg of energy, feel it fill with life and energy. This should help you a lot. Also if you wish to see a aura then look slightly away from a persons body or object, but see it with peripheral eye sight. And you can look in the mirror to see yours. Blessed be!
I'm... not entirely sure what the "light cocoon" that you were talking about is meant to accomplish, Brad. Not saying it doesn't accomplish whatever it does, just.... not quite sure what the purpose IS, strictly speaking, from your description.
That said, there isn't much that can actually be done with auras. Auras as a subconscious manifestation of energy that acts as an indication of your current mental state, and shows your place in the grand scheme of things (fate, destiny, etc. Whatever you decide to call it). Many different things can be taken away from auras, and they CAN be changed, but only by dramatically changing your own personal energy distribution. This can be accomplished with chakra therapy, or advanced energy manipulation, and is not something that I would recommend trying to anyone that's not skilled. Mainly because auras act as a constant representation of truth in the universe, and changing one's aura means changing one's truth.
Good luck in your research though. There ARE many good things to take away from advanced meditation techniques and energy manipulation techniques if you know how to proceed with them (Both of which can slightly alter your aura on their own).
Whatever the case may be, I find it promising that you're wanting to research the topic before diving head first into things. Best of luck to you in your research! Blessed be :)
Well, the stuff I was talking about is just energizing your aura. The cocoon is a meditation I use with my shaman teacher, he says it's one way to look at it and he says cocoons are the symbol of transformation. Of course feeling your aura energized in any way can help you, just whatever makes you comfortable. You may not literally feel a cocoon, just a cocoon of energy. Anyways that's all blessed be!
