Monks' evening prayer

I very seldom come to the historic section of Bangkok. It is at the other end of town. But today, I had to take a coach near Kaosan Road, a well-known street for younger travelers. While waiting for my departure to the south, I passed by this old monastery. I went in to have a look since I had never been there before. Luckily, it was prayer time for the Buddhist monks of this temple. So, I attended the ceremony and took a few pictures.
I chose this one for my blip today thinking it would be of interest to many.
