The Buddhist Teaching on Physical Phenomena
Chapter 1
The Four Great Elements

Rupas
do not arise singly, they arise in units or groups. Each of these groups
is composed of different kinds of rupa. There are four kinds of rupa, the
four “Great Elements” (Maha-bhuta rupas), which have to arise together
with each and every group of rupas, no matter whether these are of the
body or materiality outside. The types of rupa other than the four Great
Elements depend on these four rupas and cannot arise without them. They
are the following rupas:
the Element of Earth or solidity
the Element of Water or cohesion
the Element of Fire or heat
the Element of Wind (air) or motion
Earth, Water, Fire and Wind do not in this context have the
same meaning as in conventional language, neither do they represent conceptual
ideas as we find them in different philosophical systems. In the Abhidhamma
they represent ultimate realities, specific rupas which each have their
own characteristic. The Element of Earth (in Pali: pathavi dhatu), which
has been translated into English as “solidity” or “extension”, has the
characteristic of hardness or softness. It can be directly experienced
when we touch something hard or soft. We do not have to name the rupa designated
by “Element of Earth” in order to experience it. It is an element which
arises and falls away; it has no abiding substance, it is devoid of a “self”.
It may seem that hardness can last for some time, but in reality it falls
away immediately. Rupas are replaced so long as there are conditions for
them to be produced by one of the four factors of kamma, citta, temperature
or nutrition (See Introduction. This will be explained further on.). The
hardness which is experienced now is already different from the hardness
which arose a moment ago.
We used to think that a cushion or a chair could be experienced
through touch. When we are more precise, it is hardness of softness which
can be experienced through touch. Because of association and remembrance
of former experiences we can think of a cushion or chair and we know that
they are named “cushion” or “chair”. This example can remind us that there
is a difference between ultimate realities and concepts we can think of
but which are not real in the ultimate sense.
Viewing the body and the things around us as different
compositions of rupas may be a new outlook to us. Gradually we shall realize
that rupas are not abstract categories, but that they are realities appearing
in daily life. I shall quote the definitions of the different rupas given
by the commentaries, the “Visuddhimagga” and the “Atthasalini”. These definitions
mention the characteristic, function, manifestation and proximate cause
or immediate occasion (The Atthasalini explains these terms in Book I,
Part II, Analysis of Terms, 63.) of the rupas which are explained. The
“Visuddhimagga” (XI, 93) (See also Dhammasangani, § 648 and Atthasalini
II, Ch III, 332.) gives, for example, the following definition of the rupa
which is the earth element or solidity:
...The earth element has the characteristic of
hardness. Its function is to act as a foundation. It is manifested as receiving
(As will be explained, it receives the other rupas it arises together with
since it is their foundation.)...
As to the proximate cause, I shall deal with that later on.
Each reality has its own individual characteristic by which it can be distinguished
from other realities. Solidity has hardness (or softness) as characteristic,
the fire element has heat as characteristic. Such characteristics can be
experienced when they appear. As to function, rupas have functions in relation
to other rupas or in relation to nama. Solidity acts as a foundation, namely
for the other rupas it arises together with in a group, that is its function.
Smell, for example, could not arise alone, it needs solidity as foundation.
It is the same with visible object or colour which can be experienced through
the eyesense. Visible object or colour needs solidity as foundation or
support, it could not arise alone. Solidity which arises together with
visible object cannot be seen, only visible object can be seen. As regards
manifestation, this is the way a reality habitually appears. Solidity is
manifested as receiving, it receives the other rupas it arises together
with since it acts as their foundation. With regard to the proximate cause,
according to the “Visuddhimagga” (XIV, 35) each of the four Great Elements
has the other three as its proximate cause. The four Great Elements arise
together and condition one another.
At first the definitions of realities may seem complicated
but when we have studied them we shall see that they are helpful for the
understanding of the different realities, and this includes understanding
of the way they act on other realities and the way they manifest themselves.
The study of realities is a foundation for the development of direct understanding,
of seeing things as they really are.
In the “Greater Discourse on the Simile of the Elephant’s
Footprint” (Middle Length Sayings I, no. 28) we read that Sariputta taught
the monks about the four Great Elements. We read about the element of earth
or solidity, which is translated here as “extension”:
....And what, your reverences, is the element
of extension? The element of extension may be internal, it may be external.
And what, your reverences, is the internal element of extension? Whatever
is hard, solid, is internal, referable to an individual and derived therefrom,
that is to say: the hair of the head, the hair of the body, nails, teeth,
skin, flesh, sinews, bones, marrow of the bones, kidney, heart, liver,
pleura, spleen, lungs, intestines, mesentery, stomach, excrement, or whatever
other thing is hard, solid, is internal....
If the body can be seen as only elements the wrong view of
self can be eradicated. Solidity can be internal or external, outside the
body. Solidity is also present in what we call a mountain or a rock, in
all material phenomena. Sariputta reminded the monks of the impermanence
of the element of extension:
There comes a time, your reverences, when the
element of extension that is external is agitated; at that time the external
element of extension disappears. The impermanence of this ancient external
element of extension can be shown, your reverences, its liability to destruction
can be shown, its liability to decay can be shown, its liability to change
can.16 be shown. So what of this shortlived body derived from craving?
There is not anything here for saying, “I”, or “mine” or “I am”....
The impermanence of the element of solidity may manifest
itself in such calamities of nature as an earthquake, but actually at each
moment rupas arise and then fall away, they do not last.
As regards the Element of Water (in Pali: apo dhatu) or
cohesion, the “Visuddhimagga” (XI, 93) defines it as follows (See also
Dhammasangani § 652 and Atthasalini II, Book II, Ch III, 332.):
...The water element has the characteristic of
trickling. Its function is to intensify. It is manifested as holding together.
The element of water or cohesion cannot be experienced through
the bodysense, only through the mind-door. When we touch what we call water,
it is only solidity, temperature or motion which can be experienced through
the bodysense, not cohesion. Cohesion has to arise together with whatever
kind of materiality arises. It makes the other rupas it accompanies cohere
so that they do not become scattered. The “Atthasalini “ (II, Book II,
Ch III, 335) explains:
... For the element of cohesion binds together
iron, etc., in masses, makes them rigid. Because they are so bound, they
are called rigid. Similarly in the case of stones, mountains, palm-seeds,
elephant-tusks, ox-horns, etc. All such things the element of cohesion
binds, and makes rigid; they are rigid because of its binding.
We read in the above quoted sutta that Sariputta explained
to the monks about the internal liquid element (element of water):
.... Whatever is liquid, fluid, is internal,
referable to an individual or derived therefrom, that is to say: bile,
phlegm, pus, blood, sweat, fat, tears, serum, saliva, mucus, synovial fluid,
urine or whatever other thing is liquid, fluid, is internal....
When we shed tears or swallow saliva we can be reminded that
what we take for the fluid of “my body” are only elements devoid of self.
Sariputta reminded the monks that the external liquid element can become
agitated and can bring destruction to villages, towns, districts and regions,
or that the water of the oceans may go down and disappear. It is liable
to change and it is impermanent. Both the internal and the external liquid
element are impermanent and not self.
As to the Element of Fire, heat or temperature (in Pali:
tejo dhatu), the “Visuddhimagga” (XI, 93) gives the following definition
of it (See also Dhammasangani § 648, and Atthasalini II, Book II,
Ch III, 332.):
...The fire element has the characteristic of
heat. Its function is to mature (maintain). It is manifested as a continued
supply of softness. (The Atthasalini (332) states that it has “the gift
of softening [co-existent realities] as manifestation”.)
The element of heat or temperature can be experienced through
the bodysense and it appears as heat or cold. Cold is a lesser degree of
heat. The element of heat accompanies all kinds of materiality which arises,
rupas of the body and materiality outside. It maintains or matures them.
The element of heat is one of the four factors which produce rupas of the
body. Kamma produces rupa from the first moment of life and after that
temperature also starts to produce rupas of the body. Rupas which are materiality
outside such as those of a plant or a rock are produced solely by temperature.
We read in the above quoted sutta that Sariputta explained
to the monks about the internal element of heat:
... Whatever is heat, warmth, is internal, referable
to an individual and derived therefrom, such as by whatever one is vitalized,
by whatever one is consumed, by whatever one is burnt up, and by whatever
one has munched, drunk, eaten and tasted that is properly transmuted (in
digestion), or whatever other thing is heat, warmth, is internal....
The “Visuddhimagga” (XI, 36) which gives an explanation of
the words of this sutta states that the element of heat plays its part
in the process of aging: “... whereby this body grows old, reaches the
decline of the faculties, loss of strength, wrinkles, greyness, and so
on.” As to the expression “burnt up”, it explains that when one is excited
the internal element of heat causes the body to burn. The element of heat
also has a function in the digestion of food, it “cooks” what is eaten
and drunk. We may notice changes in body-temperature because of different
conditions, for instance through the digestion of our food, or when we
are excited, angry or afraid. So long as we are still alive the internal
element of heat arises and falls away all the time. When heat presents
itself and there is awareness of it it can be known as only a rupa element,
not “my body-heat”. When we are absorbed in excitement, anger or fear we
forget that there are in reality only different kinds of nama and rupa
which arise and fall away.
The element of heat can be internal or external. Sariputta
explained that the liability to change of the external heat element and
its impermanence can be seen when it becomes agitated and burns up villages,
towns, districts and regions, and is then extinguished through lack of
fuel. Both the internal and the external element of heat are impermanent
and not self.
As to the Element of Wind (in Pali: vayo dhatu) or motion,
the “Visuddhimagga” (XI, 93) defines it as follows (See also Dhammasangani
§ 648 and Atthasalini II, Book II, Ch III, 332.):
... The air element (wind) has the characteristic
of distending. Its function is to cause motion. It is manifested as conveying.
We may believe that we can see motion of objects but the
rupa which is motion cannot be seen. What we mean by motion as we express
it in conventional language is not the same as the element of wind or motion.
We can conclude that something has moved because there are different moments
of seeing and thinking, and there is association of these different experiences,
but that is not the experience of the rupa which is motion. This rupa can
be directly experienced through the bodysense.
When we touch a body or an object which has a certain
resilience, the characteristic of motion or pressure may present itself.
These are characteristics of the element of wind. It can also be described
as vibration or oscillation. As we read in the definition, the function
of the element of wind is to cause motion and it is manifested as conveying.
It is, for example, a condition for the movement of the limbs of the body.
However, we should not confuse pictorial ideas with the direct experience
of this rupa through the bodysense.
The element of wind or motion arises with all kinds of
materiality, both of the body and outside the body. There is also motion
with dead matter, such as a pot. It performs its function so that the pot
holds its shape and does not collapse.
Sariputta explained about the internal element of motion:
... And what, your reverences, is the internal
element of motion? Whatever is motion, wind, is internal, referable to
an individual and derived therefrom, such as winds going upwards, winds
going downwards, winds in the abdomen, winds in the belly, winds that shoot
across the several limbs, in-breathing, out-breathing, or whatever other
thing is motion, wind, is internal....
We may notice pressure inside the body. When its characteristic
appears it can be known as only a rupa which is conditioned. As to the
words of the sutta, “winds that shoot across the several limbs”, the “Visuddhimagga”
(XI, 37) explains that these are: “winds (forces) that produce flexing,
extending, etc., and are distributed over the limbs and the whole body
by means of the network of veins (nerves)”.
The element of wind plays its specific role in the strengthening
of the body so that it does not collapse, and assumes different postures;
it is a condition for the stretching and bending of the limbs. While we
are bending or stretching our arms and legs the element of wind may appear
as motion or pressure. We read in the “Visuddhimagga” (XI, 92):
The air element that courses through all the
limbs and has the characteristic of moving and distending, being founded
upon earth, held together by water, and maintained by fire, distends this
body. And this body, being distended by the latter kind of air, does not
collapse, but stands erect, and being propelled by the other (motile) air,
it shows intimation, and it flexes and extends and it wriggles the hands
and feet, doing so in the postures comprising walking, standing, sitting
and lying down. So this mechanism of elements carries on like a magic trick,
deceiving foolish people with the male and female sex and so on. We are
deceived and infatuated by the outward appearance of a man or a woman and
we forget that this body is a “mechanism of elements” and that it flexes
and wriggles hands and feet because of conditions.
The above quoted sutta mentions, in connection with the element
of wind, in-breathing and out-breathing. The “Visuddhimagga” (XI, 37) explains:
“In-breath: wind in the nostrils entering in.
Out-breath: wind in the nostrils issuing out.” We are breathing throughout
life, but most of the time we are forgetful of realities, we cling to an
idea of “my breath”. Breath is rupa conditioned by citta and it presents
itself where it touches the nosetip or upperlip. If there can be
awareness of it the characteristics of hardness, softness, heat or motion
can be experienced one at a time. However, breath is very subtle and it
is most difficult to be aware of its characteristic.
We read in the above quoted sutta that Sariputta explained
that the external element of motion can become agitated and carry away
villages. Its liability to change and its impermanence can be seen. Both
the external and the internal element of motion are impermanent.
As we have seen, the four great Elements always arise
together, and each of them has the other three as its proximate cause.
The “Visuddhimagga” (XI, 109) states that the four great Elements condition
one another: the earth element acts as the foundation of the elements of
water, fire and air; the water element acts as cohesion for the other three
Great Elements; the fire element maintains the other three Great Elements;
the air element acts as distension of the other three Great Elements.
We should remember that the element of water or cohesion
cannot be experienced through the bodysense, only through the mind-door,
and that the elements of earth, fire and wind can be directly experienced
through the bodysense. The element of earth appears as hardness or softness,
the element of fire as heat or cold and the element of wind as motion or
pressure. Time and again rupas such as hardness or heat impinge on the
bodysense but we are forgetful of what things really are. We let ourselves
be deceived by the outer appearance of things. The “Visuddhimagga” (XI,
100) states that the four Great Elements are “deceivers”:
And just as the great creatures known as female
spirits (yakkhini) conceal their own fearfulness with a pleasing colour,
shape and gesture to deceive beings, so too, these elements conceal each
their own characteristics and function classed as hardness, etc., by means
of a pleasing skin colour of women’s and men’s bodies, etc., and pleasing
shapes of limbs and pleasing gestures of fingers, toes and eyebrows, and
they deceive simple people by concealing their own functions and characteristics
beginning with hardness and do not allow their individual essences to be
seen....
The “Visuddhimagga” (XI, 98) states that the four Great Elements
are like the great creatures of a magician who “turns water that is not
crystal into crystal, and turns a clod that is not gold into gold....”
We are attached to crystal and gold, we are deceived by the outward appearance
of things. There is no crystal or gold in the ultimate sense, only rupas
which arise and then fall away.
We may be able to know the difference between moments
that we are absorbed in concepts and ideas and moments that there is mindfulness
of realities such as hardness or heat which appear one at a time. Mindfulness
(sati) arises with kusala citta and it is mindful of one nama or rupa at
a time. When we are, for example, stung by a mosquito, we may have aversion
towards the pain and there may be forgetfulness of realities. But when
there are conditions for kusala citta with mindfulness a rupa such as heat
can be object of mindfulness. This is the way to gradually develop the
understanding which knows nama and rupa as they are: only elements which
are impermanent and devoid of self.
As we read in the “Greater Discourse of the Simile of
the Elephant’s Footprint”, different “parts of the body” are mentioned
where the characteristics of the four Great Elements are apparent. The
aim is to see the body as it really is. When Sariputta explained about
the four Great Elements he repeated after each section:
...By means of perfect intuitive wisdom it should
be seen of this as it really is, thus: This is not mine, this am I not,
this is not myself....
Questions
1. Can the element of water be experienced through touch?
2. Can the characteristic of motion be experienced through
eyesense?
3. What is the proximate cause of each of the four Great
Elements?
