This week's entry I discovered via Joanna Powell Colbert's Gaian Tarot blog:
A site devoted to gratitude as a spiritual practice--it features a variety of meditations and exercises including a lovely virtual labyrinth walk. I just found the site an hour ago and I'm thoroughly enjoying my explorations so far.
Surfing from Gratefulness.org, I also found an entire site devoted to labyrinths that includes several more labyrinths to follow, and photographs of labyrinths all over the world. "Walking" these is a lot of fun--just follow the bird.
