Śrīmad-Bhāgavatam 7.6.1 — June 10, 1968, Montreal 680610SB-MONTREAL [65:17 Minutes] Prabhupāda: [maṅgalācaraṇa prayers] ...śalākayā cakṣur unmīlitaṁ yena tasmai śrī-gurave namaḥ [I offer my respectful obeisances unto my spiritual master, who with the torchlight of knowledge has opened my eyes, which were blinded by the darkness of ignorance.] śrī-caitanya-mano-'bhīṣṭaṁ sthāpitaṁ yena bhū-tale svayaṁ rūpaḥ kadā mahyaṁ dadāti sva-padāntikam [When will Śrīla Rūpa Gosvāmī Prabhupāda, who has established within this material world the mission to fulfill the desire of Lord Caitanya, give me shelter under his lotus feet?] vande 'haṁ śrī-guroḥ śrī-yuta-pada-kamalaṁ śrī-gurūn vaiṣṇavāṁś ca śrī-rūpaṁ sāgrajātaṁ saha-gaṇa-raghunāthānvitaṁ taṁ sa-jīvam sādvaitaṁ sāvadhūtaṁ parijana-sahitaṁ kṛṣṇa-caitanya-devaṁ śrī-rādhā-kṛṣṇa-pādān saha-gaṇa-lalitā-śrī-viśākhānvitāṁś ca [I offer my respectful obeisances unto the lotus feet of my spiritual master and of all the other preceptors on the path of devotional service. I offer my respectful obeisances unto all the Vaiṣṇavas and unto the Six Gosvāmīs, including Śrīla Rūpa Gosvāmī, Śrīla Sanātana Gosvāmī, Raghunātha dāsa Gosvāmī, Jīva Gosvāmī and their associates. I offer my respectful obeisances unto Śrī Advaita Ācārya Prabhu, Śrī Nityānanda Prabhu, Śrī Caitanya Mahāprabhu, and all His devotees, headed by Śrīvāsa Ṭhākura. I then offer my respectful obeisances unto the lotus feet of Lord Kṛṣṇa, Śrīmatī Rādhārāṇī and all the gopīs, headed by Lalitā and Viśākhā.] he kṛṣṇa karuṇā-sindho dīna-bandho jagat-pate gopeśa gopikā-kānta rādhā-kānta namo 'stu te [O my dear Kṛṣṇa, ocean of mercy, You are the friend of the distressed and the source of creation.

I am now embarrassed with this material service. Please engage me in Your service.] kaumāra ācaret prājño dharmān bhāgavatān iha durlabhaṁ mānuṣaṁ janma tad apy adhruvam arthadam [SB 7.6.1] [Prahlāda Mahārāja said: One who is sufficiently intelligent should use the human form of body from the very beginning of life—in other words, from the tender age of childhood—to practice the activities of devotional service, giving up all other engagements. The human body is most rarely achieved, and although temporary like other bodies, it is meaningful because in human life one can perform devotional service. Even a slight amount of sincere devotional service can give one complete perfection.] This instruction of Prahlāda Mahārāja to his class fellows we are discussing for the last few days.
His point of view is that this bhāgavata-dharma, or the occupational duty in relationship with God. Everyone has got some sort of engagement, occupation. Bhāgavata says, ataḥ pumbhir dvija-śreṣṭhā varṇāśrama-vibhāgaśaḥ svanuṣṭhitasya dharmasya saṁsiddhir hari-toṣaṇam [SB 1.2.13] [O best among the twice-born, it is therefore concluded that the highest perfection one can achieve by discharging the duties prescribed for one's own occupation according to caste divisions and orders of life is to please the Personality of Godhead.] Everyone is engaged in a particular type of occupational duty, never mind what is that occupation. You may be a religious priest, you may be a politician, you may be a nationalist, you may be a chemist, you may be a physist, you may be a philosopher, you may be a businessman, engineer—whatever you may be, it doesn't matter. You may be Christian, you may be Hindu, you may be dark, you may be white, whatever is there, you have got a particular type of duty.
Nobody is without any occupation. Everyone is engaged some sort of duty. The storekeeper is engaged in his business, the factory man is engaged in his business, the lawyer is engaged in his business. Everyone. So Sūta Gosvāmī said, ataḥ pumbhir dvija-śreṣṭhā varṇāśrama-vibhāgaśaḥ.
There are different kinds of duties according to the different division of the human society. That is a fact. Nobody can deny it. But how one can understand that the duty he is performing is successful?
How one can understand? What is the test? You may be whatever you are doing, that doesn't matter. But how it is tested, that whatever you have done in your whole life, it has become successful. The test is, according to Bhāgavatam, svanuṣṭhitasya dharmasya.
Everyone's duty, the point of perfection is saṁsiddhir hari-toṣaṇam [SB 1.2.13], whether by your duty you have satisfied the Supreme Personality of Godhead. That is the duty. Then it is perfect. You are a great scientist?
Very good. But if you can prove scientifically that there is God, that is successful. Otherwise, it is nonsense. If you prove that there is no God, God is dead by scientific method, it is simply lunacy, craziness. That's all.
