The human body has five organs: heart, liver, spleen, lungs, and kidneys!

These five organs are also known as the five repositories. They are organs that store, secrete, and produce vital energy. Storing essence and absorbing energy are the functions of the five organs.

In the Postnatal Realm, one cultivates vital energy and blood, transforming the Eight Extraordinary Meridians into eight rivers of blood and energy. In the Innate Realm, one cultivates spiritual energy, transforming the regular meridians into twelve long rivers of spiritual energy.

In the Divine Treasure Realm, one cultivates the five organs. Storing essence and absorbing energy, the five organs transform into the five repositories.
