Some of the canonical texts make reference to matter and atoms (called "paramāṇu", a term already used in Yajnavalkya, Lalitha Sahasranama and Yoga Sutra), including "Pancastikayasara", "Kalpasutra" and "Tattvarthasutra". The Jains envisioned the world as consisting wholly of atoms, except for souls. Atoms were considered as the basic building blocks of all matter. Each atom had "one kind of taste, one smell, one color, and two kinds of touch", though it is unclear what was meant by "kind of touch". Atoms can exist in one of two states: subtle, in which case they can fit in infinitesimally small spaces, and gross, in which case they have extension and occupy a finite space. The texts also give "detailed theories" of how atoms could combine, react, vibrate, move, and perform other actions, all of which were thoroughly deterministic.
