Walking the Tao

I had a funny occurrence at work the other day. My colleague and I were coming out of the elevator and I was just about to get my ID to open the door for her when she charged forward and opened it. She was completely lost in thoughts and did not even realize the small miracle that had just taken place. I thought for a moment about the incident and then figured it out. From the inside the door opens when you get close enough to it, so a colleague must just have triggered the light signal when he walked by. An amazing coincidence and my colleague was completely unaware that she had just walked the Tao!
