That is a very good idea. Are you a primarily visual person? Music
and soothing sounds are also quite good. Maybe you could make a "mix" for your Ipod. I have several different mixes, depending on what I'm doing---driving (I don't use headphones for this one), working out at the gym, relaxing walks outdoors in sunshine or painting.
My music list will of course be different from yours unless you are a 50-something
however I've found that anything named "zen" is usually a good choice.
Besides specific images in your book you might consider color
as therapy. For me anything blue-green is very calming, those are my favorite colors and I like to wear them in clothes and earrings and beaded necklaces I make myself (and The Moody Blues are one of my favorite groups too). I sound more like a hippie than I look lol.
Fragrance is also a calming influence as long as it isn't too strong (other peoples fragrances=ewww). Scented candles+hot water bath/shower=destressing.
Everyone has their own formula. Mine doesn't include alcohol because my colon doesn't like it, oh how I wish it did lol.
Good luck with your album. I collect photos of paintings I love, mostly Monet but also a few living painters I found online whose work is inspirational to me, landscapes mostly, of quiet places that I'd like to visit.
