Samadhi True Flame is a type of internal fire. It was originally just called "True Flame," but after the powerful True Yang Sect designated the Third Realm as the "True Flame Realm," the Upper Dan Sect stopped using the term.
The Upper Dan Sect cultivates a cauldron within their Qi Sea upon starting their journey. They use this cauldron to generate Human Fire, then nurture Earth Fire to advance to the Second Realm. Finally, they imitate the True Yang Sect's Secret Technique to devour Celestial Fire, fusing the three fires—Human, Earth, and Celestial—within their internal cauldron to form Samadhi True Flame.
