Thank you for you feed back.
I am not so sure that negative aura can affect that much real positive one. The case is, if you don't create strong positive aura around you, negative auras can impact you so easily. Like disease, it can overtake only if immune system is low and we cannot tell that our immune system is low in the situation till virus is not around, as we think we are fine. So many that impact of negative auras is actually a sign our aura is not so positive as we think so. :)
