Commentaries and Reflections
Commentary by S Ramaswami:
The question of plurality of Puruṣa.
janana- Birth
maraṇa- Death
karaṇānām- Instruments of activity.
1) From the incidence of birth and death and the endowment of the instruments of cognition and action, of activity.
pratininyamāt- Separately controlled. Separate for separate people.
2) ayugapat-pravṛtteḥ- ca- Experiences do not take place at the same time.
3) traiguṇya-viparyayāt-ca-eva- The interplay of the Guṇa is different for different people.
puruṣa-bahutvam-siddham
Because of these three reasons the Multiplicity of Puruṣa is infinite.
