True learning means knowing oneself as eternal soul, not merely acquiring worldly knowledge without self-understanding.Listen — Srila Prabhupada Uvaca
Bhagavad-gītā 2.11–12, Engagement — August 17, 1973, London 730817B2-LONDON [60:32 Minutes] Bg-02.11–12_730817B2-LONDON Prabhupāda: aśocyān anvaśocas tvaṁ prajñā-vādāṁś ca bhāṣase [Bg. 2.11] Lord Kṛṣṇa, here it is said, śrī-bhagavān uvāca: "the Supreme Personality of Godhead said." Bhagavān. It is not written here kṛṣṇa-uvāca, because people might take Kṛṣṇa as ordinary person, historical person. Therefore the author, Vyāsadeva, says bhagavān uvāca. Bhagavān means the Personality of Godhead.
Personality of Godhead…, there is definition who is Personality of Godhead. There are many persons—we are all persons. All living entities, they are individual persons. Just like you are a person, I am a person, the dog is also person, a cow is also person—everyone is individual.
But Bhagavān means the Supreme Person. As we are many persons here, sitting together, but there is some difference: they are not equal in their status of life, in their understanding, in their knowledge, in their bodily feature. Every individual person, we are not equal. I am thinking in different way, you are thinking in different way; my ambition is different, your ambition is different; my profession is different, your profession is different.
In this way, if you study each and every person, you will find there are varieties. Not that everyone is thinking in the same way or living in the same way. No. That is called person.
Everyone is individual person. Similarly, Bhagavān is also individual person. He is the supreme person—that is the difference. Just like in your country, in England, the supreme person is the Queen, but she is also a person like us.
But if we study who is the greatest personality in this country, we come to the Queen. So Queen has got a definition, who is a Queen. Similarly, when we speak of the Supreme Personality of Godhead, there is a definition. That is given in the Vedic literature by Parāśara Muni, the father of Vyāsadeva. Parāśara Muni is one of the authorities in the Vedic literature, so he has given a definition, who is the Supreme Person.
He has given, aiśvaryasya samagrasya vīryasya yaśasaḥśriyaḥ jñāna-vairāgyayaś caiva ṣaṇṇāṁ itī bhaga ganā [Viṣṇu Purāṇa 6.5.47] Aiśvaryasya means riches, wealth, one who possesses all the wealth. Now here we are sitting; say I have got one thousand dollar, you have got one million dollar, somebody has got more, more, more—you go on. But nobody can claim that "I am the possessor of all the wealth." That you cannot find. So aiśvaryasya samagrasya.
