God controls everyone or everything, but He is not controlled by anyone. That is God. Īśvaraḥ paramaḥ kṛṣṇaḥ sac-cid-ānanda-vigrahaḥ (Bs. 5.1).
And He has got form; He's a person. He's not imperson. Because as soon as you speak of controller, it cannot be impersonal. Controller must be a person. He must have brain, He must have desire, He must have capacity to give orders. So many things. So therefore the Vedic information is the Supreme Absolute Truth is a person. He's not impersonal. The impersonal realization of God is realization of His different potencies. Just like this material world, this is the manifestation of one of the potencies of God. He has got many potencies. So all the many potencies have been grouped into three: the material potency, the spiritual potency, then the marginal potency, between the material and spiritual. The spiritual potency we can understand. Just like I am speaking. I am speaking means I am spiritual being. I am speaking. This material body is my covering, just like shirt and coat. So the... Now I'm existing. Somehow or other, I've been encaged in this material body, but I am spirit soul. That is spiritual potency. And as this material world is made of material ingredients, similarly, there is another world. That information you can get from Bhagavad-gītā. Paras tasmāt tu bhāvo 'nyo 'vyakto 'vyaktāt sanātanaḥ (BG 8.20). There is another nature, another manifestation of nature. That is spiritual. What is the distinction? The distinction is when this material world will be annihilated, that will remain. Just like I am spirit soul. When this body is annihilated, I am not annihilated. Na hanyate hanyamāne śarīre (BG 2.20). After the destruction of this body, the soul is not destroyed. Soul remains there in the subtle body: mind, intelligence and ego. So that mind, intelligence and ego, that carries him to another gross body. That is called transmigration of the soul. This gross body, this body, even in our experience during this lifetime, we have experienced so many gross bodies came and went away. Just like I was a child, so I possessed one gross body, child's body. That came and gone away. I had a boy's body; that came and gone away. A young man's body I had, but that came and gone away. Similarly, this body, old man's body, it has come, and it will also go. So as in spite of so many other bodies came and went, similarly, when this body will no longer exist, I'll transfer myself or transmigrate into another gross body. This is called transmigration of the soul.
