Early Indian philosophers and ancient Greek philosophers classified matter in the from of five basic elements “Panch Tatva” - air, earth, fire, sky and water. All living and non living things are made of these five basic elements.
In our surroundings, we see a large variety of things with different shapes, size and textures. Everything in this universe is made up of material which scientists have named “Matter” for example air, food, stones, clouds, stars, plants and animals, even a small drop of water. The perception of joy, love, hate, thought, cold, hot, pain does not constitute matter while we perceive.
