Wat Pho is the only temple in use within a city that I went inside during my trip to Thailand. I’m not sure what drew me in, but I’m glad I went.

While I was there I was able to watch a ceremony. I’m not sure what it was for but here is a little info about the type of ceremony.
White string is often used in ceremonies such as prayers during holidays, house blessings, monastic ordination, etc. The purpose of these strings is to transfer the benefits of the blessing directly down to each of the participant. Sometimes those strings (that are connected to Buddha’s wrist) hang down from the ceiling and people wrap them around the top of their head, which is considered the holiest part of the body. These white strings will then be cut into small pieces after the completion of the blessing ceremony and attached around the wrists of visitors for good luck.
