- dve virūpe carataḥ svarthe : Two great mothers (Aditi-mother of gods who are aware of their divine origin and Diti-mother of beings who are unaware of their origin) march towards the same goal (which is to make the world for the habitation of non dual divine which existed before creation). 

- anyānyā vatsam upa dhāpayete : They take turns to feed the child (who is the original non dual divine born to these mothers)
- harir anyasyām bhavati svadhāvāñ : (non dual divine through Aditi ) he becomes sun (super mind/Vijnana) who is the master of his nature.

- chukro anyasyāṃ dadṛśe suvarcāḥ : (Through Diti) he is born as the bright soul/fire that guides beings in the darkness
