Here it is said in the Seventh Chapter, śrī-bhagavān uvāca. Bhaga. Bhaga means opulence. You use the word bhāgyavān, bhāgya. From this word, bhaga, it has come bhāgya. Bhāgya means fortune, opulence. So Bhagavān means all-fortunate, all-opulent. That is Bhagavān. That definition is given by Parāśara Muni.
When we speak "Kṛṣṇa," please try to understand I am speaking of the Supreme Lord. Kṛṣṇa means "all-attractive," Bhagavān. Here it is said in the Seventh Chapter, śrī-bhagavān uvāca. Bhaga. Bhaga means opulence. You use the word bhāgyavān, bhāgya. From this word, bhaga, it has come bhāgya. Bhāgya means fortune, opulence. So Bhagavān means all-fortunate, all-opulent. That is Bhagavān. That definition is given by Parāśara Muni. The wealthiest man, aiśvaryasya samagrasya. Aiśvarya means wealth, and samagra means all, complete. We may be very rich; you may be very rich; but nobody can claim that "All the riches belong to me." Nobody can say. Only Bhagavān can say. Just like Kṛṣṇa says in the Bhagavad-gītā, bhoktāraṁ yajña-tapasāṁ sarva-loka-maheśvaram (BG 5.29). He says, "I am the enjoyer of all activities." Just like there are so many different types of activities, but the result of the activity is enjoyed by somebody. He is called bhoktā. Just like in a very big business establishment so many activities are going on, but the enjoyer of the result of the activities is the proprietor or the managing director, something like that. Similarly, Kṛṣṇa says, bhoktāraṁ yajña-tapasām. We are engaged in different types of austerities, penances, and performing yajñas, but who is the bhoktā? Bhoktā, Kṛṣṇa says, "I am the bhoktā, I am the enjoyer." Bhoktāraṁ yajña-tapasāṁ sarva-loka-maheśvaram: "And I am the proprietor of everything within this universe." Not only in this universe, there are many other millions of universes. Therefore says, sarva-loka-maheśvaram. There are different lokas in each and every universe. And maheśvaram, mahā īśvara, the supreme proprietor. Bhoktāraṁ yajña-tapasāṁ sarva-loka-maheśvaram, suhṛdaṁ sarva-bhūtānām (BG 5.29). Although He is so great, still, He is friend of all living entities. Sarva-loka-maheśvaram, suhṛdam... jñātvā māṁ śāntim ṛcchati. This is the culture. If anyone can understand that God is the proprietor of everything, God is the enjoyer of all activities, the resultant action, God is the supreme friend of everyone—simply by understanding these three formulas, one attains real platform of peaceful life. That is peaceful life.
So bhagavān uvāca. We don't say anything which is not spoken by Bhagavān, the Supreme.
