Pegs for personal use which are sometimes worn on the body and used for meditation and ritual use are generally plain in appearance and thin in girth. Sometimes they will have one or three wrathful (raksha) heads. For Hayagriva practitioners they will have a horse head at the top. A more elaborate Hayagriva peg might have three horse heads.
