A Book

Another way of praying is with a book.  But be willing to put down the book the moment you feel inspired to rest with a phrase or idea that comes from your reading.  Spiritual paths have books.  There is the Bible, the Koran, the Sutras, the Tao, the Vedanta, the Upanishads, and the Big Book of Alcoholics Anonymous.  Plenty of good ideas for meditation in all that.  So why torture yourself trying to come up with good thoughts to feel better, or for meditation?  Let the book do it for you.
