According to ancient Daoist energetic anatomy and physiology, humans have three important energy centers that store and emit energy similar to the same way a battery stores and emits energy. These three centers are called the Three Dantians. The Three Dantians are strategically positioned along the Taiji Pole in order to facilitate maximum energy transference.
Although the chakra systems are more significant in the Buddhist and Yogic traditions, both of these spiritual disciplines commonly refer to the Three Dantians areas in their energetic practice. According to ancient Buddhist and Yogic traditions, these three areas contain the three psychic knots or "Granthi" where an individual's energy and spiritual consciousness interact and manifest in particular ways.
