Prabhupāda: Sir Alistair Hardy. He came. He admitted. He's making research. So these things are going on. Why research? Everything is there in the Bhagavad-gītā. Everything is explained and commented by so many, many great, stalwart, I mean to say, commentator, especially Śrīdhara Svāmī, Rāmānujācārya, Viśvanātha Cakravartī, Baladeva Vidyābhūṣana. So many great scholars, they have commented upon Bhagavad-gītā. So try to understand Bhagavad-gītā as it is. That is the real necessity of life. That we have explained several times.
This human form of life. The . . . Narottama dāsa Ṭhākura says that hari hari bifale janama goṅāinu: "My dear Lord, Hari, I have simply spoiled my life." Bifale jan . . . hari hari bifale janama goṅāinu. "I have wasted my time." Why? Manuṣya-janama pāiyā, rādhā-kṛṣṇa nā bhajiyā, jāniyā śuniyā biṣa khāinu: "I got this nice human form of body especially for worshiping Rādhā and Kṛṣṇa, but I have not done that. Therefore willingly I have drunk poison." Jāniyā śuniyā biṣa khāinu. Golokera prema-dhana, hari-nāma-saṅkīrtana. The saṅkīrtana movement is not manufactured in this material world. It is released from Vaikuṇṭha, the spiritual world. Golokera prema-dhana . . . otherwise, why you are chanting Hare Kṛṣṇa, Hare Kṛṣṇa . . .? It is not material sound. Any material sound, you chant thrice, you'll be tired. But you go on chanting Hare Kṛṣṇa mantra twenty-four hours, you'll never be tired. Therefore it is not a sound of this material world, it is the sound of the spiritual world. Golokera prema-dhana, hari-nāma-saṅkīrtana, rati nā janmilo kene tāy, "I am not attracted to this." This is the lamentation of Narottama dāsa Ṭhākura, a Vaiṣṇava. Biṣāya-biṣānale, dibā-niśi hiyā jvale: "In this material existence, this eating, sleeping, mating and defending, with this business always my heart is burning." Biṣāya-biṣānale, dibā-niśi hiyā jvale, taribare nā kainu upāya. "I did not make any means to get out of this." Golokera prema-dhana. Therefore indirectly he's giving hint that human life is meant for worshiping Rādhā-Kṛṣṇa and chanting Hare Kṛṣṇa mahā-mantra.
