Śāstra-vākya-pramāṇa. And it should be known through the spiritual master. Just like nowadays Bhagavad-gītā is being interpreted in so many foolish ways, because they do not accept explanation from the authority. They become themselves authorities. Therefore misused. That is not explanation. Somebody is explaining that Kurukṣetra means this body, pañca-pāṇḍava means the senses. These are all nonsense. You have to accept Bhagavad-gītā as it is.
When you cannot understand, you should get it explained by your spiritual master. Therefore one has to accept a spiritual master to understand. Tad-vijnanārtham. In order to understand that transcendental science one must approach the bona fide spiritual master. That is injunction.
So here it is said that kānyakubje dvijaḥ. Dvijaḥ means he was offered the sacred thread. That means he was born in a Brahmin family. Janmanā jāyate śūdraḥ. Everyone is born a śūdra, a foolish. Sudra means a foolish man who simply laments. That is the real meaning of śūdra. Anyone who has no intelligence, he is śūdra. We also generally say gadāh, less intelligent.
So brāhmins, kṣatriyas, vaiśyas, they are called higher caste. According to their . . . Brahmin, first class, because his intelligence is first class. Kṣatriya, his intelligence is second class. Vaiśya, his intelligence is third class. And śūdra means fourth class. And less than śūdra, they are called pañcama, caṇḍāla. They are accepted as animals, those who are less than śūdra. This is the Vedic system.
Now here it is said that this Ajāmila, dvija . . . Dvija means he was properly initiated, second birth. First birth by father, mother, is śūdra. Anyone, even if he is born in a Brahmin family, the natural birth is considered as śūdra. But if there is garbhādhāna-saṁskāra, then he's accepted as born Brahmin. Born Brahmin. Still, one is born Brahmin, he has to undergo the saṁskāras.
So our this . . . Now it is known as Hindu society, although the "Hindu" word is given by the Muhammadans. It is called sanātana-dharma, or varṇāśrama society, who very strictly follow the four divisions, social divisions, of varṇa—brāhmin, kṣatriya, vaiśya, śūdra—and four division of spiritual life—brahmacārī, gṛhastha, vānaprastha and sannyāsa. So our . . . the Vedic system is called varṇāśrama.
Varṇa means this social order, and āśrama means spiritual division. Therefore those who are following strictly the Vedic principle, that family life is called gṛhastha āśrama. Āśrama. Whenever you add this word āśrama there is spiritual significance.
