So the prakṛti cannot give birth to the varieties. That is wrong theory. That is wrong theory. The real variety begins when the prakṛti is in touch with the Puruṣa. That is our experience also. How we can say that prakṛti can give birth or woman can give birth to a child or many children without being touch with man? Where is our experience? There is no such thing. Therefore we should not take prakṛti as everything. We must find out the Puruṣa. Therefore the puruṣa who gives birth to these material varieties, that is Lord Śiva, and the prakṛti which gives birth to these varieties, that is Durgā. Therefore the original prakṛti and puruṣa is represented by śiva-liṅga, and devī-patha(?). Those who are worshiper of śiva-liṅga, they know the devī-patha(?) and the śiva-liṅga, they are worshiped. The original father, Kṛṣṇa, says, ahaṁ bīja-pradaḥ pitā: "I am the seed-giving father." Sarva-yoniṣu kaunteya sambhavanti mūrtayo yāḥ (BG 14.4). There are varieties of forms of life. How they are being begotten? Kṛṣṇa says, ahaṁ bīja-pradaḥ pitā. That pitā, father, is Lord Śiva.
So when Kṛṣṇa comes in touch with prakṛti for giving birth of these varieties of forms of life, that is Śiva. That is Śiva. Śiva is not different from Kṛṣṇa, but still, Śiva is not Kṛṣṇa. This is called inconceivable one and different. Inconceivable one and different. The example is given: just like milk and yogurt, dahi. Dahi is not different from milk. It is milk—it is milk, everyone knows—but it is not milk at the same time. You cannot get the benefit of milk by drinking dahi, or yogurt. Milk is used for different purpose, and dahi is different purpose. When you take too much milk, you get dysentery, and if you go to the physician, he gives you some medicine to take with yogurt, dahi. So dahi or yogurt, is not different from milk, but it is not milk. Similarly, all these demigods, especially Lord Śiva, Lord Brahmā... They are the original chief demigods from Viṣṇu.
So these demigods or even we... We are also the same principle, the living entities. Brahmā is also in the category of living entities, and Lord Śiva is between the living entities and the Supreme Lord, in between. Therefore you cannot keep Lord Śiva as living entity category, neither Viṣṇu category. Via media. Kṣīraṁ yathā dadhi vikāra-viśeṣa-yogāt (Bs. 5.45). The Supreme Personality of Godhead does not come directly in touch with this prakṛti, but the form by which He touches this prakṛti, that is Lord Śiva. Therefore Lord Śiva is not different from the Supreme Personality of Godhead; at the same time, he is not the Supreme Personality of Godhead. This is the conclusion.
