Acharya Kannad and the Vishesika sutra




Kanada (Sanskrit: कणाद); was a sage and philosopher who founded the philosophical school of Vaisheshika and authored the text Vaisheshika Sutra. He probably lived around the 2nd century BCE,while other sources claim he lived in the 6th Century BCE. It is believed that he was born in Prabhas Kshetra (near Dwaraka) in Gujarat,India.

His primary area of study was Rasavādam, considered to be a type of alchemy. He is said to have believed that all living beings are composed of five elements: water, fire, earth, air, ether. Vegetables have only water, insects have water and fire, birds have water, fire, earth and air, and Humans, the top of the creation, have ether—the sense of discrimination (time, space, mind) are one. He theorized that Gurutva(Hindi/Sanskrit for Gravity) was responsible for the falling of objects on the Earth.

He is recognized as the founder of atomic theory, and classified all the objects of creation into nine elements (earth, water, light or fire, wind, ether, time, space, mind and soul). He stated that every object in creation is made of atoms that in turn connect with each other to form molecules nearly 2,500 years before John Dalton. Further, Kanad described the dimension and motion of atoms, and the chemical reaction with one another.

These Indian ideas about atom and atomic physics could have been transmitted to the West during the contacts created between India and West by the invasion of Alexander.

Many believe that Kanada originated the concept of atom. An interesting story states that this theory occurred to him while he was walking with food in his hand. As he nibbled at the food in his hand, throwing away the small particles, it occurred to him that he could not divide the food into further parts and thus the idea of a matter which cannot be divided further came into existence. He called that indivisible matter as ' Anu ' .i.e. atom.
