Sukh could not sleep for many nights. Then, when finally he slept one night, he dreamed of the white horse. The horse said to Sukh, “Don't be sad. Please makea musical instrument out of my bones and hair. If you make it, I can always be with you." Sukh made the musical instrument, the horsehead rebec. After that, Sukh always took the horsehead rebec with him. When he played it, he felt that his white horse was with him. That sound moved the hearts of all the people of Mongolia.
