Simplicity and Renunciation

Meditation retreats offer a sacred space protected and removed from the world. They allow participants to look deeply inside, quiet their minds, and open their hearts. The most beneficial and rewarding spiritual life experiences often happen at a meditation retreat. The sheltered and quiet setting is crucial for developing patience, steadfastness, lovingkindness, generosity, joy, and wisdom.

These are the seeds that grow insight, compassion, and happiness. Participants are requested to let go of concerns for daily life and embrace an attitude of simplicity and renunciation by adopting a traditional spiritual practice called “taking what is offered.”

Taking What is Offered

Taking any Practice Space —whatever accomodations are offered. We ask participants to happily accept the assigned accommodation and continue practicing this spirit throughout the retreat. Shoes are not allowed in the Sanctuary.
Taking Food that is Offered—Happily accepting food that is offered is part of the practice. The cook lovingly prepares tasty and nutritious meals. Gluten-free alternatives will be available for those with medically required dietary restrictions. Participants with other special dietary needs may arrange with the retreat manager to bring supplemental food items with them to the retreat. Food is prohibited in the Sanctuary and kitchen.
Silence – In fostering an atmosphere of contemplation and meditation, participants are expected to embrace the practice of silence during the retreat. Living in silence is the practice of observing within and not communicating with others. This includes reading or writing, telephones, computers, email, or text messages. Talking is permitted during the evening dhamma talks and teacher interviews when questions are encouraged. Inquiries about the retreat may be directed to a retreat manager or whenever necessary in the case of an emergency.

COVID-19

There are currently no COVID-19 public health safety state or local mandates. There are no vaccination requirements at The Harmonist Sanctuary. As a precaution, we ask that participants do a home test before they arrive. As an additional safety measure, take another home test on the opening day of the retreat and a further test on the following morning.
