Horsehead vajrayana is a small column standing at the four corners of the altar, also known as square branch or four branches. Its basic shape is a triangular dagger, but the decoration on the handle is quite different. Some handles are Buddha's heads, some are Guanyin bodhisattva statues, wearing a five-bone crown and a horse's head at the top. The purpose of the Horsehead Vajrayana is to set it at the four corners of the altar, so that the Dojo is as strong as King Kong and all kinds of evil forces can't hurt it.
Ba Pu vajra, also known as vajra vajra, is an instrument with one end in the shape of vajra and the other end in the shape of a pointed triangular pyramid. There are three Buddha heads as handles in the middle, one laughing, one angry and one scolding. Ba Pu's Vajrayana is usually used to practice the method of surrender, which is used to subdue demons and resentment, indicating that it has powerful magic.
