Hara
Equivalent to the lower Dan Tien and the Muladhara chakra. Equivalent in physical terms to the sexual organs and the related systems that govern the hormones here.
In Chinese, Korean, and Japanese traditions, the hara is called the ‘physical center of gravity of the human body and is the seat of one's internal energy ‘.
A master of calligraphy, swordsmanship, tea ceremony, martial arts, among other arts, is held in the Japanese tradition to be "acting from the hara".
