How it is evidenced is quite similarly described by anyone on this path. People, especially those we do not know, see something so different about our entire countenance that they just have to comment. I have witnessed this with my wife whose light body at times seems to be palpable.
So, it is not surprising to find people coming up to comment positively about how we look.
For me, I have noticed lots and lots of smiles coming my way- apparently for no reason.
If you are one working at awakening, be ready for others to see your awakening glow and be open to their desire to connect. Perhaps this awakening is after all, quite contagious.
