what was the qualification of Śukadeva Gosvāmī which induced Vyāsadeva to teach him this saṁhitām? Śukam adhyāpayām āsa nivṛtti-niratam (SB 1.7.8): he has no more attraction for material world. That is the qualification. Nirvṛtti. There are two kinds of life: nirvṛtti and pravṛtti. Pravṛtti means materialistic, karmīs. Generally karmīs, they have got tendency to enjoy this material world. That is called pravṛtti. Pravṛtti-mārga. Pravṛttes tu . . . Pravṛtti is natural inclination. Anyone who has come to this material world . . . Pravṛttir eṣā bhūtānām. Everyone is in the pravṛtti-mārga. What is that pravṛtti-mārga? The pravṛtti-mārga is these things: sex, meat-eating, intoxication, like that. This is pravṛtti-mārga. Pravṛttir eṣā bhūtānāṁ nivṛttes tu mahā-phalām.
So the whole Vedic literature is there how to make him stop this pravṛtti-mārga. That is the whole plan. Otherwise, there are many instances, loke vyavāyāmiṣa-madya-sevā nityas tu jantuḥ (SB 11.5.11). Nitya. A jantuḥ . . . He's called jantuḥ. Jantuḥ means animal, or no intelligence. Those who are jantuḥ, they have got this tendency, pravṛttir eṣā. What is that? Vyavāyāmiṣa-madya-sevā: sex and meat-eating. Āmiṣa, meat, egg, fish; and madya, intoxication. This is pravṛtti. Loke vyavāya. Vyavāya means sex. Āmiṣa-madya-sevā nityā tu jantuḥ. Jantuḥ means living being, conditioned in the material world, they have got this general tendency, pravṛtti. You will find in animals, in birds, in beasts, and beastly human being, two-legged beast . . . There are four-legged beasts and two-legged beasts. Four-legged beasts are the animals—cats, dogs, tigers, etcetera. Cows, asses - they are four-legged beasts. And there are two-legged beasts, dvi-pāda-paśu. It is not manufactured; it is there in the śāstra. Dvi-pāda-paśu. Dvi means two, and pāda means legged. So any human being who is attached to this pravṛtti-mārga—sex, meat-eating, intoxication, gambling—he is dvi-pāda-paśu, two-legged animals. This is pravṛtti-mārga.
Therefore education should be in such a way planned that he should be nirvṛtti-mārga. Pravṛttir eṣā bhūtānāṁ nirvṛttes tu mahā-phalām. These are general tendency for the conditioned soul. But if anyone can control by training, by education, these things—vyavāyāmiṣa-madya-sevā: sex life, intoxication and meat-eating—then he's called niratam. He becomes qualified. Vyāsadeva preferred to teach Śrīmad-Bhāgavatam to his son Śukadeva Gosvāmī, because he was niratam, nivṛtti-niratam. He was engaged. From the very beginning of his life, as soon as he was . . . It is said for sixteen years within the womb of his mother, he did not come out purposefully, so that he may not be materially attached. Because a small child, the baby, comes out from the mother's womb. Within the womb, when he's in suffering, he prays to God, "This time kindly release me. Now I shall begin bhagavad-bhajana." One who is little advanced in his previous life . . . Because it is very, very terrible condition within the womb of the mother. We have forgotten. But we can imagine, if you are packed up in a bag and put hand and legs tightly knotted, just imagine. You cannot live even for three minutes. They say if you are airtight packed-up like that, as we are put into the womb of the mother, we cannot exist more than three minutes. But we existed by the mercy of Kṛṣṇa. Only by the mercy. That is also nowadays very dangerous. In that packed-up condition, he's there, he's already suffering, and the mother is planning to go to the doctor and kill the child. Just imagine how precarious condition in the womb of the mother. And if we do not try in this life that "I shall not again enter into the womb of the mother," then what is the value of this life? We have to learn it from the śāstra. You cannot see actually, but the medical science explains that a child is placed in this way. In Bhāgavata also it is stated how the child grows his body, how it is put into that precarious condition.
