So Kṛṣṇa, by His Paramātmā feature, He is all-pervading. He is in all universes. He is all, everywhere, in the heart of all living entity. Īśvaraḥ paramaḥ... Īśvaraḥ sarva-bhūtānāṁ hṛd-deśe 'rjuna tiṣṭhati (BG 18.61). And He is also within the atom. Aṇḍāntara-stha-paramāṇu-cayāntara-stham (Bs. 5.35). Aṇor aṇīyān mahato mahīyān. This is Kṛṣṇa. So one has to understand Kṛṣṇa perfectly. So for preliminary study of Kṛṣṇa, there is Bhagavad-gītā, how to understand Kṛṣṇa. And next... Bhagavad-gītā is the ABCD, primary entrance to the understanding of spiritual life. This is ABCD. But people are so fallen that they cannot understand even ABCD, what to speak of becoming graduate or postgraduate. In this age people are so fallen. This Mahābhārata... Mahābhārata was given by Vyāsadeva for the less intelligent class of men: strī-śūdra-dvija-bandhūnāṁ trayī na śruti-gocarā (SB 1.4.25). Śruti means Vedas. Vyāsadeva considered that stri, woman; śūdra, the fourth-class men... Strī-śūdra-dvija-bandhūnām... Dvija-bandhu means those who are born in higher-class society—brāhmaṇa, kṣatriya, vaiśya—but they are not qualified. They are simply proud of getting birth in higher families. They are called dvija-bandhu. They are equal to woman and the śūdra. Strī-śūdra-dvija-bandhūnāṁ trayī na śruti-gocarā. Trayī means the Vedas. Karma-kāṇḍa, jñāna-kāṇḍa, upāsana-kāṇḍa. There are three methods in understanding Vedas, and their language, their process, is very difficult. Therefore Vyāsadeva, considering the immediate inauguration of Kali-yuga... Because Vyāsadeva appeared at the end of Dvāpara-yuga. So before writing these Vedas, Vyāsadeva, by Vyāsadeva, there was no written scripture. Therefore these Vedas are called śrutis. People learn it simply by hearing, śruti. Śrotram. Śrotriyam. Tad-vijñānārthaṁ sa gurum eva abhigacchet śrotriyaṁ brahma-niṣṭham (MU 1.2.12). Śrotriyam means the guru must be (an) expert who has heard from his bona fide spiritual master. That's śrotriyam, not śaukram. Śaukram means generation by semina. And śrotriyam, generation by hearing from the bona fide spiritual master. Śrotriyaṁ brahma-niṣṭham. After hearing, one must be firmly fixed up in brahma-jñāna. Brahma-niṣṭham. This is called śrotriyam.
So dvija-bandhu means who has not perfected his knowledge by hearing from the bona fide source. He is called dvija-bandhu. And the śūdras have no facility, neither the woman has got the facility to go to the gurukula and become a brahmacārī and remain there and learn the Vedic literature. Because women were not allowed, neither could follow. It is not discrimination. It is actual fact by nature. There may be some exception, but by nature it is so fixed up. So for them, this Mahābhārata, greater history, or history of greater India, Mahābhārata...
