Bhaga means opulence. Just like we sometimes speak "bhagavān." That comes from this word bhaga. Similarly, bhagavān. Bhagavān means the owner of all opulences. That is called bhagavān. There are now, nowadays, so many bhagavāns, but they are not owner of all opulences. Maybe partly. But God means, bhagavān means, samagrasya. Samagra means complete. One rich man can claim that, "I am owner of so many crores." Another can claim, "No, I have got one or two more crores more than you." Others may say . . . . so on, so on, so on, go on. But nobody can claim that "I am the owner of all opulences." But in the Bhagavad-gītā you will find, Kṛṣṇa claims, bhoktāraṁ yajña-tapasāṁ sarva-loka-maheśvaram (BG 5.29). Sarva-loka-maheśvaram, "The supreme proprietor of all the lokas." That is admitted by the śāstra.
In the Brahma-saṁhitā it is said, īśvaraḥ paramaḥ kṛṣṇaḥ (Bs. 5.1). Īśvara means controller, or the powerful man who controls. Take, for example, the president or the king. So there are many īśvaras, or controller. You are also īśvara; I am also īśvara. Because you also control at least your family members or some animals. So this controlling capacity is there in everyone, because we are part and parcel of Kṛṣṇa. But we are not supreme controller. We are controller of some entities, but we are controlled also by something superior. Therefore we are not absolute controller. We are relative controller. But about Kṛṣṇa it is said, īśvaraḥ paramaḥ kṛṣṇaḥ (Bs. 5.1). Paramaḥ means supreme. He controls everyone or everything, but He is not controlled by anyone. That is īśvaraḥ paramaḥ. We are īśvara. We control to . . . in our jurisdiction, but we are also controlled by somebody. Just try to understand. But in Kṛṣṇa's life you'll find that He controls everyone, but He is not controlled by anyone. Therefore He is called īśvaraḥ paramaḥ kṛṣṇaḥ.
Sac-cid-ānanda-vigrahaḥ (Bs. 5.1). He has got His form. God has got His form. The Māyāvādī philosophers, they think the Absolute Truth is impersonal, śūnyavādi. No. Absolute cannot be zero or impersonal, because controller, controller must have brain. Without brain, how he can control? And as soon as you have got brain, you have got other limbs of the body to carry out the order of the brain. So as soon as you have got senses, as soon as you have got sense organs, as soon as you have got brain, as soon as you have got activities, you are a person. This is the conclusion of the śāstra. Therefore the absolute controller cannot be impersonal. By our practical life we see—government. "Government" is an impersonal word, but at the end of the government, there is a governor or president, a person. A person is required, who will apply his brain. So how is that, that without brain the whole cosmic manifestation, it is controlled? That is not very reasonable. And that is not according to śāstra.
