In this sacred philosophical discourse the Supreme Godhead declares Himself as the begetting father, who impregnates the seeds of living entities in the womb of mother nature who in turn gives birth to all varieties of living entities or species. So the plain truth is that the Supreme Godhead the Father, the nature material is the mother and all living entities are so many children of almighty father Godhead, and the mother nature. The whole arrangement is just a family unit, and we should wonder as to why there is so much anomaly in this great universal family unit.
The answer for this is also given in the Bhagavad-gita. It is said that there are two classes of men in the creation. One class is called the devas (godly) and the other class is called the asura (demonic or godless). As sons of the almighty Father Supreme Godhead, all individual living individuals have their respective independence. One can utilize this god-gifted independence properly or improperly.
When a living entity improperly uses god-gifted independence and apply such independence for sense-gratification without fulfilling the will or the plan of Godhead, he at once develops the demonic qualities in contact with the illusory Energy of Godhead and becomes a full-fledged asura. But one who do not misuse the God gifted independence and does not engage himself in the act of sense-gratification but fulfills the plan of the Godhead, continues to be a deva or godly. In this act of sense-gratification the asura children of Godhead forgets the plan of Godhead and therefore tries to exploit the state of Godhead for their own benefit which is sometime centralized but sometimes extended. The gods or the godly sons of Godhead do not act like this and they are therefore distinguished from the asuras.
