Kanada — also called Kashyapa and Uluka — is the traditional author of the Vaisheshika Sutra, one of the six classical darshanas. His dates are uncertain; scholars place the sutras anywhere from the sixth to the second century BCE. His name, "grain-eater", is explained by a story that he lived on grains left in the fields after harvest — or, as others say, because he thought in terms of the smallest particles.
यतोऽभ्युदयनिःश्रेयससिद्धिः स धर्मः“Dharma is that from which come prosperity and the highest good.”Vaisheshika Sutra 1.1.2
The Vaisheshika school, later joined with Nyaya (logic), became one of the most influential systems of Indian philosophy.
The world in particles
Kanada taught that the physical world is made of paramanu, indivisible and eternal particles of four kinds — earth, water, fire and air — which combine in pairs and triads to form the objects we see. When things break down, they return to these particles. Space, time, mind and the self are also counted as substances, but are not made of atoms.
Six categories of reality
To describe everything that can be known and named, Vaisheshika lists six padarthas: substance (dravya), quality (guna), action (karma), universality (samanya), particularity (vishesha) — which gives the school its name — and inherence (samavaya). A seventh, absence (abhava), was added later. This careful analysis made Vaisheshika a tool for thinking clearly about the physical world.
A science in a spiritual frame
Though remembered today for its atomism, the Vaisheshika Sutra begins by promising to explain dharma, and holds that right knowledge of the categories leads to liberation. Prashastapada's commentary (c. 6th century CE) systematised the school, and Nyaya-Vaisheshika logicians debated Buddhists and others for centuries.
How they are remembered
Modern Indians often cite Kanada as an early thinker of atomic ideas — though his atoms were a philosophical, not an experimental, theory. His categories remain basic to Indian logic and are still taught in traditional Sanskrit schools.
