The monks destroyed the sand mandala as a metaphor of the impermanence of life, then distributed half the sand to the audience. The other half is traditionally poured into a nearby body of water. In this case, the monks went to the Spokane River and deposited the sand into the falls near Canada Island.

As part of the ceremony, prayers were offered in the Spokane language to respect the ancestors and the river.
Ven. Tritul Jampa Kalden poured the sand into the river.
