Misogi is also used in some forms of martial arts, especially aikido, to prepare the mind for training and to learn how to develop one's Dantian, or centre. The founder of aikido, Morihei Ueshiba, regularly used this form of meditation to complement his training and search for perfection. The Sen Shin tei Misogi Well at Ki Society Headquarters in Japan is a well-known place for people performing misogi with cold water before sunrise.
