Kṛṣṇa says:
- sarva-yoniṣu kaunteya
- sambhavanti mūrtayaḥ yāḥ
- tāsāṁ mahad yonir brahma
- ahaṁ bīja-pradaḥ pitā
- (BG 14.4)
Aham. Kṛṣṇa says that, "All these living entities in 8,400,000's of species . . ." He doesn't mean that only human being. The animals, the birds, beasts, trees, everything—all living entities—they are all sons of God. He says, ahaṁ bīja-pradaḥ. The material nature is the mother.
Just like in ordinary way, the father and mother requires to give a birth to a child. Similarly, this material nature is the mother. We have got this body from the mother, material nature. Just like we get the body from the mother's womb. Father gives the seed and mother gives the body. In the combination we get out. Similarly, ahaṁ bīja-pradaḥ pitā (BG 14.4): Kṛṣṇa impregnates this material nature with the living entities, and when there is creation they come out. This is the process.
So we are fallen in this material condition of life, and because we have disobeyed without the permission of father, we have misused our independence; therefore we are condemned within this material world. The īśāvāsya, the Īśopaniṣad teaches us, therefore reminds us that, "My dear human being . . ." The śāstras, the scriptures, the Vedas, they're meant for human being, not for the dogs, cats. Those who are not taking advantage of these scriptures of Vedic literatures, they are no more than animals. Because animals, they cannot take advantage of this knowledge. But human being can take.
Therefore it is said, indicated, in the śāstras, that this body is very suitable boat for crossing over this ocean of nescience. We are in the ocean. This outer space, the big space within this universe, it is to be considered just like a big ocean, and all the planets, they're just like islands. Therefore in the Vedic literature sometimes these planets are called dvīpa. Dvīpa means island. Śvetadvīpa. This planet is called Jambūdvīpa. Just like in the ocean, there are many hundreds of small, big island. Similarly, the ocean of air or outer space, there are so many planets. They are called dvīpas.
So īśāvāsyam . . . so all this belongs to God. And we, we are, because we are His sons, we have got the right to use our father's property, but not illegally. What is allotted to us by our father we can accept it. That's all. One who lives . . . that is stated in the Īśopaniṣad that, kurvann eveha karmāṇi jijīviṣec chataṁ samāḥ (Īśo mantra 2).
