But the process of this generation is somewhat more complex. A Tanmátra first disintegrates and emanates in a surrounding medium (a menstruum) of the Tanmátra just preceding it in the order of genesis and with the help of its own Sthúla Bhúta as a sort of catalytic, generates the Tanmátra next in order; e.g., the infra-atomic impact particles (स्पर्श तन्मात्र) disintegrate or emanate, in a surrounding ‘atmosphere’ of the vibratory subtile matter (शब्द तन्मात्र) and then with the help of their own atomic integration Váyu, gas, generate the Tanmátra next in order, the subtile matter of radiant light-and-heat (तेजः). - [Previous: v2.c34.120](https://indike.org/pramana/ins.science.ray-1902.v2.c34.120) - [Next: v2.c34.122](https://indike.org/pramana/ins.science.ray-1902.v2.c34.122) - [Up: v2.c34](https://indike.org/pramana/ins.science.ray-1902.v2.c34) --- Source: [https://indike.org/pramana/ins.science.ray-1902.v2.c34.121](https://indike.org/pramana/ins.science.ray-1902.v2.c34.121) · Pramāṇa
