Five Elements
The ancient rishis (sages) understood the universe in the context of the five elements: earth, water, fire, air, and ether. Everything in the world, from humans to couches, is a combination of these five elements.
Sometimes it’s difficult to conceptualize this from a scientific point of view. I like to think of it as similar to saying everything in the world is composed of atoms of oxygen, carbon, nitrogen, etc. We can break down everything in the universe to a few basic components. In ayurveda, the basic components are the 5 elements; in modern science, the basic components are represented in the periodic table.
These 5 elements are more than their physical form–they represent ideas. So really, the ancient sages broke down everything in the universe into ideas, and categorized them as the 5 elements as follows:
Earth: Represents solidity and stability
The earth element encompasses the solid forms of matter (e.g. wood, metal, plastic) and the concepts of stability (e.g. mental, structural) and solidity.
Water: represents flow and fluidity
Water encompasses the liquid form of matter (e.g. juice, rain, liquid mercury). This element has no inherent motion of it’s own, but conceptually represents flow–which is always along the path of least resistance. Flow can be seen in nature, in the body, but also in the dynamic between two people, or traffic. Fluidity can be seen in the mind–flowing with compassion, generosity and being willing to move along the path of least resistance.
Fire: represents light, heat, and transformation
The combustion reaction that is taking place in fire (e.g. wood to ash) represents the transformation governed by this element. Fire encompasses the force that allows a species to evolve, people to change, and food to be transformed into macromolecular nutrients in the body. This element governs the digestion of food and thoughts.
Air: represents motion
Any movement in the universe, whether inside a cell or of a planet, is governed by this element. In the body the air element is responsible for movement of nerve impulses, breath, and our muscles.
Ether: represents connectedness or space
This element is the most ambiguous one, and thus the most strange to conceptualize. I think of this as the space that the other elements fill. We can’t sense ether, so just think of outerspace. In the body, ether governs our body cavities and spaces (e.g. sinuses, pelvic cavity); in the mind, consciousness.
