The image shows an elderly man wearing a red robe, standing in front of a blackboard in a classroom. He is writing on the blackboard with white chalk and appears to be in the middle of a lesson. The blackboard is filled with various mathematical equations and formulas written in different languages. On the right side of the image, there is a bookshelf and a colorful tapestry hanging on the wall. The man seems to be focused on his work and is likely a Buddhist monk.
