So our business is to understand Kṛṣṇa tattvataḥ, in truth, not superficially. Then our life is successful. Janma karma me divyaṁ yo jānāti tattvataḥ (BG 4.9). Not superficially. Try to understand Kṛṣṇa in truth. Therefore here it is said that tāni me śraddadhānasya kīrtanyāny anukīrtaya. Anukīrtaya. Anukīrtana means don't manufacture. Anu means following. Therefore the bhagavat-tattva, or Bhagavān, can be understood by the paramparā system. Anu. Evaṁ paramparā-prāptam imaṁ rājarṣayo viduḥ (BG 4.2). Rājarṣayaḥ. Formerly, the kings, they were rāja, at the same time great saintly persons, ṛṣi. They were not ordinary this king, Nawab Shah, engaged in drinking and dancing. No. They were all ṛṣis, all ṛṣis. Up to Mahārāja Parīkṣit they were trained up in such a way. Although it was monarchy, one man's control, but that man is not ordinary man. They were called nara-deva. Nara-deva means Bhagavān in the form of a human being. A king was worshiped therefore, because they were rājarṣi. Imaṁ rājarṣayo viduḥ. Bhagavān says, Kṛṣṇa says. Unless the kings, the government head, does not know what is the purpose of this life, what is the purpose of this material world, then how he can rule nicely? It is not possible. He has no purpose. He does not know what is the aim of life. Just like they think that eating, sitting..., eating and sleeping and sex life and then die. They're like animal life. This is not human life. Human life must know what is the aim of life. That they do not know. Na te viduḥ svārtha-gatiṁ hi viṣṇuṁ durāśayā ye bahir-artha-māninaḥ (SB 7.5.31). These foolish people, they are trying to be happy-durāśayā. Durāśayā means the hope will never be fulfilled. That is called durāśayā. Bahir-artha-māninaḥ. Bahir-artha-māninaḥ. These external... Here is called ātma-māyayā. But there is another māyā. This māyā is external māyā, external energy. That is this material world. They are trying to be happy in this material world by adjusting material things. That is called durāśā. It will be, never be fulfilled.
Therefore in the history we see, there have been so many material leaders, but they died simply working hard. They could not make things very properly adjusted. There was Napoleon, there was Hitler, there was Gandhi, there was Nehru, there were so many leaders. But nobody could adjust. This is not possible. That is durāśā. Durāśayā ye bahir-artha-māninaḥ. Because they do not know what is the ultimate goal of life. The ultimate goal of life is to understand Viṣṇu. And people are going on.
