The kaana-sah was the name given to a series of exercises performed by Borothan pilgrims. They were designed to purify the body.

Doctor Phlox participated in these exercises while on a visit to a ship transporting Borothan pilgrims to observe the Great Plume of Agosoria. He remarked he might have strained a leg muscle in doing so, but it was well worth it. (ENT: "Cold Front")
