Beautiful St Andrew's Cathedral

I sat in St Andrew's Cathedral today, soaking up the calm and tranquility.

I don't suppose it matters that I don't have a religious bone in my body. I presume it's okay to just go in and sit. However, I do feel obliged to at least consider the option of religion if I'm using their pew to sit and have a ponder. I usually end up wondering what everyone else is thinking though. Religion fascinates me.
