The Tattvarthasutra is said to be generated from the aggregation. In this way, there are aggregates from the meeting of atoms up to the categories of tri-pradesha, chatursh-pradesha, sankhya-pradesha, asankhya-pradesha, anant-pradesha, and anant-anant-pradesha. All of them are generated from aggregation. The smaller aggregates that result from the breaking of several large aggregates are considered to be generated from differentiation. These can also range from two pradeshas to anant-anant pradesha. When one aggregate breaks, and a new aggregate forms at that moment with several substances from its elements, that aggregate is generated both from differentiation and aggregation. Such aggregates can also exist from dhri-pradesha to anant-anant pradesha. For aggregates with two or more regions, it should be understood that the tri-pradesha, chatursh-pradesha, etc., can arise from the meeting of three, four, or other different atoms. Moreover, when an atom combines with an aggregate of tri-pradesha, it could lead to a formation of a tri-pradesha or a duo-pradesha, and similarly, when one atom combines with the chatursh-pradesha aggregate, it could create a chatursh-pradesha aggregate.
Atomic substances do not perform the work of different substances. Therefore, in their origin, it is not possible for two substances to unite. Thus, atoms are considered eternal. However, the origin explained here is such that, from the perspective of their definitions, atomic substances are indeed eternal but also generated. Sometimes atoms reside in a communal state as components of an aggregate, and at other times they exist separately in a distinct (scattered) state—these all represent different states of the atom.
