Devotionals depend upon the Pagan.  Emmanuel's Book is such a devotional, although it does not contain anything direct from the Gaidheal.  Be considerate when asking for a Pagan or New Age devotional.  Ask a bookstore or retailer about it.  If you feel nervous, tell the retailer that you are seeking a book about Paganism and detail the devotional.  Use a dream journal to take down notes.  They will be useful.
