Does watching a bonfire cleanse my aura or just calm my mind?

It is our family ritual that every new year, we will go for a bonfire. And every time I sit near the bonfire, I can feel peace and stillness like never before. Even while doing meditation i dont feel like it. Could aura cleansing with aura be naturally happening because I am not chanting or anything or meditating.... or is it just a psychological comfort?
