Just like we have got experience, the father injects the living entity in the womb of the mother, and the mother, by her blood, develops the body of the child. Similarly, all these living entities, 8,400,000 species, the . . . bījo 'haṁ sarva-bhūtānām (BG 7.10). The father is Kṛṣṇa. He has given the seed in the womb of this material nature. And the material nature has given the body. Somebody has got the body of fish, somebody has got the body of tree, plant, somebody has got insect, reptile, somebody bird, sometimes beasts, somebody human being, somebody demigod. But all these materials have been supplied by the mother. It is very easy to understand. Just like the child grows, the mother supplies the bodily ingredients.
Caitanya Mahāprabhu therefore . . . this is very scientific. When He took sannyāsa and the mother came . . . Advaita Prabhu arranged to see for the last time her son. Because a sannyāsī is no more coming home. So at that time, mother became overwhelmed, "Such beautiful body. He has nice hair. Now it is shaven." So she became very much overwhelmed and was crying. So Caitanya Mahāprabhu immediately fell down on her lotus feet and He said: "My dear mother, this body is yours." "My dear mother, this body is yours. This body should have been engaged for your service, but some way or other, I mistake; I have taken this sannyāsī. Kindly excuse Me." Caitanya Mahāprabhu said that, that "This body belongs to you. This is your body." Every son should think like that. This is Vedic culture.
Actually, the body supplies, mother. From the very beginning, after sex . . . these are all described in the Bhāgavatam. The two secretions become emulsified, and a body is formed just like a pea and gradually develops. The ingredients, the energy is supplied by the mother. So the same thing. The whole creation, the body is supplied by material nature, mother. Therefore she is called "mother."
Material nature is called "mother," Mother Durgā. Sṛṣṭi-sthiti-pralaya-sādhana-śaktir eka, the material nature, and her name is Durgā.
- sṛṣṭi-sthiti-pralaya-sādhana-śaktir ekā
- chāyeva yasya bhuvanāni vibharti durgā
- icchānurūpam api yasya ca ceṣṭate sa
- govindam ādi-puruṣaṁ tam ahaṁ bhajāmi.
- (Bs. 5.44)
This is description of Durgā. So Kṛṣṇa also says. So we should not think like that, that animals or trees or birds and beast, they are other than ourself. They are our brothers, because the seed-giving father is Kṛṣṇa, and the mother is material nature. So we have got the same father and same mother. So if we have got the same father and mother, they are all our brothers.
