In the two ancient mythological novels "Journey to the West" and "Fengshen Yanyi", there have been Samadhi True Fire, in "Journey to the West", the red child punched his nose twice, you can spew out Samadhi True Fire, Sun Wukong used Samadhi True Fire, the elixir in the body into a piece, so as to obtain the incorruptible body of King Kong. In the "Fengshen Yanyi", Taiyi Zhenren sacrificed the Nine Dragon Divine Fire Shield to subdue Shi Ji Niangniang, and finally used the Samadhi True Fire to burn shi Ji Niangniang back to its original form, and Jiang Ziya spewed out the Samadhi True Fire in his eyes, nose and mouth when he was in the Song City, and burned the jade pipa essence back to its original form.

In mythological novels, there is often a samadhi true fire, so what is the samadhi true fire? Which samadhi is it referring to?
In fact, the four words of Samadhi True Fire should be taken apart to see that Samadhi is a Buddhist term, while True Fire is a Taoist term, and the Samadhi True Fire in the novel is actually a manifestation of the fusion of Buddhism and Taoism.
Samadhi' real name in Buddhism is Samadhi, which is a way of practicing that can be simply understood as eliminating all distractions and concentrating. In fact, similar to the practice of meditation, there are many related records, such as: "All meditation, also known as ding, also known as samadhi." "With the heart legitimate, away from evil and chaos, so it is called samadhi." ”
All in all, the buddhist concept of "samadhi" is inseparable from a "heart" word, and the word "true fire", which is more simple and clear in Taoism, is the fire in the heart, which also represents the vigorous vitality.
Of course, there are other different accounts of samadhi in the true fire of samadhi, which are considered to represent three different substances.
The first is the essence, the qi, and the spirit
In the "Fengshen Yanyi", when Jiang Ziya surrendered the jade pipa essence, he described in detail the composition of the Samadhi True Fire, and in the original work, it was said: "This fire is not an ordinary fire, it will spew out from the eyes, nose, and mouth, but it is the essence, qi, and god refined into samadhi, and the cultivation is separated from the essence, and it is together with the mortal fire, how can this goblin withstand it?"
From this, we can see that the samadhi in the true fire of samadhi represents essence, qi, and god.
The second theory is fire in wood, fire in stone, and fire in the air
The Pure And Honest Daode True Emperor has a magic weapon called the Five Fires and Seven Birds Fan, also known as the Five Fire God Flame Fan and the Seven Plume Fans. Among the five fires, including wood fire, stone fire, and air fire, it is considered to be the true fire of Samadhi.
The third theory is the fire of kings, the fire of ministers, and the fire of the people
In the Taoist classic "Finger Xuan" written by Lü Dongbin, it is said: "The heart of the Junhuo, also known as the Divine Fire, its name is Shangming, the kidney is also called Jinghuoye, its name is Zhongxia, the bladder is the bladder, that is, the navel qi sea, the people's fire, its name is Xiaxia. ”
The fourth saying is the fire of the eye, the fire of the mind, the fire of the pneumatics
The ancients also called the fire of sight, the fire of consciousness, and the fire of pneumatic movement collectively known as the true fire of Samadhi, and these three kinds of fires are combined together, and when the mind is aggravated, they are called martial fire, when the mind is relaxed, they are called Wenhuo, and the two are also called Wenwuhuo.
Taishang Laojun threw Sun Wukong into the Bagua furnace and practiced it for 7749 days, using the Wenwu Fire, which was essentially the True Fire of Samadhi.
