The energy that emits through the combination of a soul and its physical body is known as Aura,
Aura reflects the essence of Karma that revolves around oneself ,
If you feel peaceful around the presence of a being whether human or an entity it is the rippling effect of their Aura ( their constant struggles to seek peace from within and around),
That says, what your are feeling in their presence is what you seek as well .
Unconditional karma
