Śrī bhagavān uvāca. Bhagavān, the Supreme Being, Bhagavān. In your English dictionary the word God is explained as "the Supreme Being." Supreme Being means who is great, greater, or the greatest, of all other beings. We are beings. We are individual persons. It is not very difficult to understand. Every one of us, individual. We think individually. We dress individually. We have got our egotism, individual. Everything. I don't agree with you; you don't agree with me. Voluntarily sometimes we agree. That means every one of us has individuality. This is called being. "I am."
Similarly, God is also being like us, but He is Supreme Being. That is the difference between God and me. I am also being, you are also being, but we are not Supreme Being. We are under some control. But God is not under control. He is the controller, but He is never controlled. (aside:) Make it louder. That is explained in the Vedic literature, the definition of God. The definition of God is given there, īśvaraḥ paramaḥ. The Supreme Being is Kṛṣṇa. Īśvaraḥ paramaḥ kṛṣṇaḥ sac-cid-ānanda-vigrahaḥ (BS 5.1). And He is . . . Vigraha means He has form. He is person, sac-cid-ānanda-vigraha. But His person, His form, is different from our form, our present form. Our present form, as we have got the material tabernacle, that is temporary. Your form, my form, this is changing. We are not existing in the same form. Just like we have got this form, human form of life. It is not permanently I shall be able to enjoy. Just like you have got a particular dress now. It is not permanent. You can change your dress any moment. Similarly, this body, material body, is considered . . . Actual fact: it will not endure. We'll have to change. Therefore it is not sac-cid-ānanda-vigraha.
But Kṛṣṇa's form is sac-cid-ānanda. Īśvaraḥ paramaḥ kṛṣṇaḥ sac-cid-ānanda-vigrahaḥ (BS 5.1). Vigraha means form. So everyone has got form. There are 8,400,000 forms of living entity. In the water there are 900,000 forms. Jalajā nava-lakṣāṇi sthāvarā lakṣa-viṁśati (Padma Purāṇa). Amongst the trees, plants, there are 2,000,000 forms. So there are hundred and thousands of forms in the material world. But in the spiritual world the form is sac-cid-ānanda-vigraha. Every form is eternal, full of knowledge and full of bliss. That is the difference between material world and spiritual world. Material world means . . . Although the varieties are there in the spiritual world . . . There are also trees, as well as we have got here trees. But there the forms are spiritual form, and here they are material form. Material form and spiritual form, what is the difference? The difference is that just like a living being . . . I can ask any of my disciple to do something, he'll do it. But this microphone, it has also a form, but if I want microphone, "Please do this," he cannot, it cannot be, because it is material. It can mechanical, give some mechanical service, one only, but it cannot do any other thing. A man can speak or he can dance or he can become a thief, he can become so many—because he's living. That is the difference between material form and spiritual form. Therefore in the Bhagavad-gītā the material forms, they have been described as inferior, and spiritual forms . . . There is spiritual world also. That is called parā-prakṛti. There is another nature.
