Can you look in the mirror? What an idiotic question! Of course, I can. I do it everyday when I brush, shave or comb. Then why is my friend asking this question of whether I can look in the mirror. These were the thoughts running in my mind immediately after my friend asked this question, pointing his fingers at me accusingly.
My friend has a point though he framed the question in a simple and misleading manner. There are many people in the world who cannot see themselves in the mirror. Don't mistake it for vanity. They are not like this because they hate their faces. They have done so many deeds in their lifetime for which there are ashamed now. There is no redemption. As a result, they have come to a point where they cannot stand seeing themselves. It is a sorry state to be in.
In spiritual terms, the question is same as "Can you see your soul?". This is a serious question. Can you? I cannot. I can barely pierce into the superficial flesh that adorns my soul. In a way, it is good. You don't worry a lot about something you can't see. Still there is a simple advice for you. Don't do anything that will make you shy away from mirror or soul (whichever you are able to see with minimal efforts).
