YOGA.jpgYoga, Nature, and Soulfulness
September 10-12, 2021  

Let's restore, explore, and discover by immersing ourselves in the gifts of yoga and nature to unite with our soulfulness! This weekend includes physical yoga practices, meditation, hiking, and dharma discussions. Some of our sessions will be held outdoors as Mother Nature allows. Both yoga and nature can help us open gateways to our innermost selves. When we soulfully touch nature, we touch ourselves. By going outward, we journey inward finding a soulful connection to spirit and the divine.

Included in the retreat: two nights of lodging(dorm-style with private bathroom), 6 meals, 4 sessions with the instructor, Gigi Heinz. The retreat begins with dinner at 5 p.m. on Friday and ends with lunch on Sunday.

Cost: $312.50 lodging with a roommate or $382.50 for single lodging.

Register by texting Gigi at 715-297-6540. Payments can be sent online through Venmo, or a check payable to: Gigi Heinz at W6606 Sunset Drive, Merrill, WI 54452.
