I’ve been a fan of Beliefnet.com for a long time. The site provides information and resources for the worldwide variety of religious practices, as well as an interesting questionnaire to determine what religions are closest to one’s personal beliefs (there is a caveat that states they are not responsible for one’s immortal soul, lol).
A number of daily or weekly newsletters, such as a daily Bible reading and weekly Buddhist prayers, are available from the site. The article referenced above explains ways to use nature to meditate and find peace. In my opinion, they could be used by members of most religions as they are not dependent on any particular dogma.
