So I was reading online about aura balancing techniques and how to balance your aura. What are the pros or cons of balancing and everything about it? So yesterday while I was doing meditation, they went to meditation every once in a while to feel calm and peaceful. Yesterday when I was doing it, I slept a lot better. So, is this my aura balancing naturally? Like does meditation help in aura balancing or taking rest helps in aura balancing? I want to know more about it because I want to follow it more. It's really good that I got a very sufficient amount of sleep and felt really fresh in the morning so I want to follow this technique of aura balancing.
