Wai Khru Muaythai is a tradition which goes back to ancient times, it is not an optional ritual or reserved for special occasions: the official Muaythai regulations[1] specify that both fighters must perform the Wai Khru Ram Muay before each and every bout. It’s a tradition in which fighters pay respect to their teachers, parents and things they hold sacred and pray for their safety and victory. The ritual has been developed in different ways, in different regions, even under different teachers and therefore it is theoretically impossible for two fighters to perform identical Wai Khru.

The Wai Khru is graceful and aesthetic ritual, both practical and spiritual. In a practical sense, it functions as a final pre-fight warm-up and gives the fighter some time alone before the fight to collect his thoughts. It can be divided into three main sections:
• The Royal Homage Sequence
• This was originally intended to show devotion to the King, going back to the days when fighters were selected to display their skills in front of him. It has three subsections: Prostration, Outstretched Arms and Act of Homage.
• The Kneeling Sequence
• This section is performed in a kneeling posture, one knee on the ground and the other leg out in front. the fighter pivots around on the spot to repeat the same sequence facing all four sides of the ring, a tradition which comes from Krabi Krabong.
• The Standing Sequence

In this section, the fighters go out from the center of the ring in one direction, to perform the Dramatic Interlude. Some fighters imitate the motions of “Rama Shooting an Arrow” from the Ramakien, a hunter, a soldier, or an executioner. Some fighters use this ritual to attempt to scare their opponents, commonly by stomping around them. But in a deeper sense, the fighter is expressing religious devotion, humility, and gratitude. Transcending both physical and temporal limitations, he opens himself to the divine presence and allows it to infuse his heart.
