This article by Rabbi Ruth Adar from ReformJudaism.org provides advice and tips for those who are new to Jewish prayer and may be concerned about not understanding the words, customs or structure of the service. Although the article is written with prayer in a synagogue in mind, it is a useful resource for those who will be visiting the Western Wall and want to understand more about Jewish prayer. Perhaps more important than anything, remember that prayer is about your personal connection with God; feel free to pray from the heart in any language!
