Hinduism
The system of five
elements are found in Vedas,
especially Ayurveda,
the pancha
mahabhuta, or "five great elements", of Hinduism are bhūmi (earth),[6] ap or jala (water), tejas or agni (fire), marut, vayu or pavan (air or wind)
and vyom or shunya (space or zero) or akash (ether or void).[7] They further suggest that all of
creation, including the human body, is made up of these five essential elements
and that upon death, the human body dissolves into these five elements of
nature, thereby balancing the cycle of nature.[8]
The five elements
are associated with the five senses, and act as the gross medium for the
experience of sensations. The basest element, earth, created using all the
other elements, can be perceived by all five senses – (i) hearing, (ii)
touch, (iii) sight, (iv) taste, and (v) smell. The next higher element, water,
has no odour but can be heard, felt, seen and tasted. Next comes fire, which
can be heard, felt and seen. Air can be heard and felt. "Akasha"
(aether) is beyond the senses of smell, taste, sight, and touch; it being
accessible to the sense of hearing alone.[9][10][11]

While the
classification of the material world by the ancient Indians and Greeks into
Air, Earth, Fire and Water was more philosophical, during the Islamic Golden Age medieval
middle eastern scientists used practical, experimental observation to classify
materials.[3] In Europe, the Ancient Greek
system of Aristotle evolved slightly into the medieval
system, which for the first time in Europe became subject to
experimental verification in the 1600s, during the Scientific Revolution.
Centuries of empirical investigation have proven that all the ancient
systems were incorrect explanations of the physical world. It is now known that atomic
theory is
a correct explanation, and that atoms can be classified into more than a
hundred chemical
elements such
as oxygen, iron,
and mercury.
These elements form chemical
compounds and mixtures,
and under different temperatures and pressures, these substances can adopt
different states
of matter. The most commonly observed states of solid, liquid, gas,
and plasma share many attributes with the
classical elements of earth, water, air, and fire, respectively, but it is now
known that these states are due to similar behaviour of different types of
atoms at similar energy levels, and not due to containing a certain type of
atom or a certain type of infinitely divisible substance or energy.
--- Origin of the
world – Wikipedia.
Origin and definition of the terra firma –
Temporal world.
“ The earliest extant grammatical treatise Tolkappiam and other successive classical
literary texts define the world as a combination of five elements – earth, air,
fire, and water. Ancient literary texts in Greece and Egypt also reiterate the
same concept. But nobody is able to observe how these five elements originated
and at what stage and how they synthesized themselves into the formation of the
physical world, as we see it now. Hence a conceptual definition of the world
in a way acceptable but origin of the
world is unknown and mysterious.
In the absence of any tangible explanation for the origin of the world,
Puranic texts attribute it to the activities of God. But still what is known as
‘Atomic theory’ alone seems to be plausible.” –Editor.
