Of courses. The Templestay program is open to everyone, regardless of religion, gender, or race. It's a place where everyone can come together and have a unique culturl experience. If any of the activities will be hard for you due to your religious beliefs, just let the instructor know in advance.
Templestay programs normally run from two to five days in length.However, there is a temple that offers a “trial ordination” program for about a month. It’s also possible to simply take a rest at some temples for a longer period of time. Check out the Templestay website for more detailed information.
There are many places that run Templestay programs focused on children or young adults during the school holiday periods. Among these programs for kids, most tend to focus on cultural experiences or ecological awareness. You can take a look at the guidebook for more detailed information on the different programs each temple offers, or else visit the website at http://www.templestay.com
Anyone who is in decent physical shape should be able to do the Seon (Jap: Zen) meditation or 1080 bows. Only a few participants have found that 1080 bows or other practices are too much for them. It’s important to keep the proper attitude of acting together with others, so don’t be fixed on the numbers, just go at your own speed.
