Chi (read both as ki and qi), also known as Lifeforce, is the energy that flows inside all living beings.
Chi is a metaphysical and ubiquitous power used by living beings to perform nearly all actions.
The control over chi is developed mainly through training and meditation and may enhance natural physical and mental abilities, such as strength and accuracy. Chi can also increase one's lifespan or even make one immortal. Many members of Gautama are known to have an extended control over chi.
Ascension is a process which releases one's true potential through either meditation or a great trauma (rarely, death), as a result of extreme chi manipulation.
