Meditate For A Week Or The Full Month of Dathun
A Retreat In The Colorado Rocky Mountains

Now Offering Free Tuition! Pay Only Lodging and Meals.

A Dathun is a month or week-long meditation retreat based on the understanding that meditation is always experienced in a social context and that our path is tremendously supported by an awake and kind environment. This retreat will join the practices of Shambhala meditation and shamatha, or mindfulness, meditation, with an emphasis on using the retreat container as a basis for generating loving kindness. We will use every part of our day, including eating together, serving each other, meditating together, individual meditation instruction and daily teachings, to support each other on our paths. Please join us for this precious opportunity to engage in the practice of meditation.
