Other possibilities for meditation in the Seattle area (with focus on N. Seattle)
There are dozens of groups that offer meditation in Seattle and the surrounding area. Often, the best way to find them is using our friend, google. Using the 'maps' link and searching for "meditation" near me, I found 6 groups within about a mile from my home. It'll be up to you to do some research. Is the meditation Taoist, secular, Zen, Transcendental, Jewish or otherwise? Are their requirements for registration, preliminaries, etc. It's always helpful to find out more before you go. But then go, as the Buddha said, "see for yourself."
Below are a few links to get you started.
