A *bhuta*-atom is evolved by integration (condensation and collocation) from the corresponding *tanmatra* (subtile matter) The *tanmatras* again evolve from one another in a lineal series as in Parasara's view described above. But the process of this generation is somewhat more complex. A *tanmatra* first disintegrates and emanates in a surrounding medium (a menstruum) of the *tanmatra* just preceding it in the order of genesis, and, with the help of its own *sthula bhuta* as a sort of catalyst, generates the *tanmatra*, next in order e g., the infra-atomic impact particles (*sparsa-tanmatra*) disintegrate or emanate in a surrounding atmosphere of the vibratory subtile matter (*sabda-tanmatra*), and then with the help of their own atomic integration *vayu* (gas) generate the *tanmatra* next in order, the subtile matter of radiant light-and-heat (*tejas*)
