The ultimate principle of India’s the doctrinal teaching of the four great material elements was referred to earth, water, fire, and air. It is understood as the species of four great material elements, which means that it is the basis of the creation of all material in Buddhism’s Abhidharmakosa Shastra. Also in the West, Empedocles persisted that earth, water, fire, and air are the four great elements because they are the basic elements of all material things in the universe.
Therefore earth, water, fire, and air are the ultimate reality of the universe, claimed both by the east and the west under the same opinion.
Without the presence of earth, water, fire, and air, it is not possible to sustain life on earth. All living creatures can exist, due to the existence of the four great elements. Also because of the four great elements, culture can be formed after humanity flourishes.
The earth, water, fire, and air have both Yang which involves the meaning ‘Hot’ and Yin which involves the meaning ‘Cold’. It’s like a Magnet, it consists of N and S pole.
The earth is.:
There are two elements for earth, which are cold and hot. Therefore Yin and Yang exist on earth.
The water is.:
There are two elements for water, which are cold and hot. Therefore Yin and Yang exist on water.
The air is.:
There are two elements for wind, which are cold and hot. Therefore Yin and Yang exist on air.
The fire is.:
There is the only one element for fire, which is hot. There’s no such thing as ‘cold fire’.
Therefore fire is the standard of earth, water, fire, and air. The criteria unchangeable, and unchangeable one should be always the basic root.
The only way to govern all matters when things are not changed. Hence, “Everything in the universe is changeable, but things that are always changeable never change.” in the I Ching(周易).
In conclusion, the fire is the criteria of all changeable things in the universe and the root is what makes things changeable.
The presence of fire refers to the center of the solar system. All the planets that exist in the solar system revolve around the sun with pinpoint accuracy. The solar system would not have existed without proper order of the planets. It would came crashing down without the sun which is the heart of the solar system.
That is why the sun is the center of the solar system. The sun is the absolute being, that has only energy of Yang. Here, the meaning of Yang is not a relative term that compares between Yin and Yang, but the Yang here only means ‘an absolute sense’.
It is same reference by Lao-tzu, who was an ancient Chinese philosopher, which is “The meaning of Wu(nothing, 無) is not a relative term of Yu(existence, 有), but it is absolute meaning of Yu(existence, 有)”.
This absolute being of ‘the fire’ is also a criterion of oriental medicine
In oriental medicine, the five viscera was attached by oriental five vital elements:
Wood (木 mù), Fire (火 huǒ), Earth (土 tǔ), Metal (金 jīn), and Water (水 shuǐ).
Wood is Liver.
Fire is Heart.
Soil is Spleen.
Iron is Lungs.
Water is Kidneys.
The heart is likened to the monarch in oriental medicine. It means that the heart being is a vital organ like a king of the human body. The heart is in charge of circulation inside the visible structure of the blood vessels (血脈), mental consciousness and thought activities, and the function of life activities in the human body (神明).
In other words, the heart deals with ‘Blood and Mind’ which is the most important and most in need for human and to form all cells and organs inside the body.
Blood does not circulate when the heart stop, even if other organs are healthy. Eventually human being dies because of the end of the life energy, which is the function of life activities in the human body (神明).
Thus, when the heart stops, all human beings are mortal naturally.
In medical science, the heart is the most unique organ than others and the criterion.
The fire is criteria for all material, and the origin that makes material appear. However the fire is not the form that occurs itself, but it is the supreme that makes everything appear.
The fire that has a potential consciousness is hidden or stored inside of all material.
That is why the fire inherent in all material is sparked when one rubs itself against the other.
For instance, a wood rubs against the other, a fire sparks, a stone strikes against the other, a fire sparks, rubbing together one’s hands, a fire sparks, and an iron strikes against the other, a fire sparks. Fire exists inside all materials and become life’s energy that releases from and to all shapes and forms.
As the fire is potentially stored inside of all materials, it indicates that a fire also exists inside of the human body as well.
‘The Mind’ is this potential fire.
For instance, if what we see is our mind, our eyes are the objects. If what we hear is our mind, our ears are the objects. The innate mind which moves the human body is inherent inside of our body and is what drives us to continue our life.
An ancient sage said this,
“Free all ignorance and bondage through the flames of wisdom.”
When our inner mind manifests itself and starts to grow, a light will awaken the ignorance and the bondage of the world.
In order to manifest the light from inside of our mind, we can use meditation as a tool. My body is a tree and meditation creates another one. From the friction between two trees, the hidden fire from the seams manifests itself rises to the surface. Likewise meditation brings you wisdom and true self which are hidden inside of the body.
We could set a fire from the tool of meditation to bring out the true fire that is inherent inside our body. For someone who can meditate there’s nothing cannot be done with concentration of the mind. After I started to do meditation, I became to like wearing sun colored clothes, similar to as if I was the center of my own universe. I said the criteria in the universe. Also in order to concentrate on myself, I learned to practice without any disturbance.
