Domesticated draught animals, like yaks, dzo, oxen, and cattle, are tamed and claimed by piercing the animal's nose.  In Tibet, nose rings are made from flexible branches of young trees often found on mountaintops. This riddle specifically mentions a branch acquired at Drak mar: a famous red stone cliff behind Samye monastery. The selected branch is then stripped of its bark and whittled so that it tapers from the thickness of a finger on one end to a point on the other. The pin is then twisted into a ring and placed in the animal's nose. This process allows the tamer to bring more peaceful, controllable behavior to the individual animal, and by extension, the surrounding pastures.
