When we speak of universe, we cannot think of. They simply calculate, the scientists, by light-year and this year, that year, the speed. But we cannot approach even in this material world, and what to speak of Kṛṣṇa? Kṛṣṇa is in the spiritual world. We cannot calculate the length and breadth of this material world, our knowledge is so imperfect and meager, and what we can understand of the spiritual world? The material world is a manifestation of Kṛṣṇa's one-fourth energy. And the three-fourth energy is manifested in the spiritual world. This is the understanding of Kṛṣṇa.
Therefore when one inquires about Kṛṣṇa, he is very glorified. Therefore he says, varīyān eṣa te praśnaḥ. Varīyān eṣa te praśnaḥ kṛto loka-hitam (SB 2.1.1). Because answer to this question will include everything, and people will profit there, loka-hitam. The saintly person duty is to do welfare to the people in general. That is saintly person. Lokānāṁ hita-kāriṇau tri-bhuvane mānyau śaraṇyākarau. About the Gosvāmīs, ṣaḍ-gosvāmī, it is stated that nānā-śāstra-vicāraṇaika-nipuṇau. The six Gosvāmīs, they were very, very learned scholars, nānā-śāstra, various different scriptures, vicāraṇaika-nipuṇau, very expert in studying all the scriptures scrutinizingly, nipuṇau, expert. This is the, I mean to say, calculation of the Gosvāmīs. So why they are concerned about studying so many scriptures? Now, sad-dharma-pracāraṇa. Nānā-śāstra-vicāraṇaika-nipuṇau sad-dharma-saṁsthāpakau. Sad-dharma. Dharma means . . . the exact meaning of dharma is "occupational duty." People are . . . in English they translate dharma as "faith." Faith can be changed. I like this faith today; tomorrow I may like another faith. So actually the translation of dharma is not "faith." It is "occupational duty."
So what should be our occupational duty? Sad-dharma. Sad-dharma means . . . sat means eternal. Real occupational duty . . . now I am working as American, or others working as Indian or German or Englishmen, or this family men. Everyone has got some occupational duty. But this occupational duty . . . suppose I am working as American or European or Australian. This is temporary, because this body is temporary. And I am in bodily concept of life, therefore my duty, so-called duty, is also temporary.
