The description of Ajivikas' atomism is inconsistent between those described in Buddhist and Hindu texts. According to three Tamil texts, the Ajivikas held there exists seven kayas (Sanskrit: काय, assemblage, collection, elemental categories): pruthvi-kaya (earth), apo-kaya (water), tejo-kaya (fire), vayo-kaya (air), sukha (joy), dukkha (sorrow) and jiva (life). The first four relate to matter, the last three non-matter. These elements are akata (that which is neither created nor destroyed), vanjha (barren, that which never multiplies or reproduces) and have an existence independent of the other. The elements, asserts Ajivika theory in the Tamil text Manimekalai, are made of paramanu (atoms), where atoms were defined as that which cannot be further subdivided, that which cannot penetrate another atom, that which is neither created nor destroyed, that which retains its identity by never growing nor expanding nor splitting nor changing, yet that which moves, assembles and combines to form the perceived.
