Homonym: Shin (Heart)
Shin is a term that can refer to various concepts, but it is often associated with the Japanese word for "new" or "true." In the context of martial arts, particularly Aikido, it can denote a state of mind or approach that emphasizes authenticity and sincerity in practice.
In another context, Shin can refer to the shinbone, which is the long bone in the lower leg, known as the tibia. It plays a crucial role in supporting the body's weight and facilitating movement, connecting the knee to the ankle.
