The Theosophical Society of America, based in Wheaton, has a regular Sunday morning meditation group. There is no charge, but donations are appreciated.
The group meets in the library and meditation starts at 11. This is a seated meditation and chairs are provided, but you you can bring cushions.
The library is in the main building on the campus. We'll meet up in the lobby at 10:45. Note - this is the library and not the Quest Bookstore which is visible from Geneva Road.
From their website:
Each week, a topic related to meditation will be presented and discussed, followed by a brief guided meditation and longer silent meditation. Instruction will be provided for beginners, but practitioners of all levels are encouraged to share their path of meditation.
Afterwards we can head to the Red Apple Pancake House (north on Schmale Road/Main St Wheaton).
