From that primordial source arose the Grāmya and Āraṇyaka portions, along with the composition of sacred mantras. These Grāmya and Āraṇyaka sections, together with the mantras, are known as the Ṛg, Brāhmaṇa, and Yajus. In a similar manner, the Taittirīyas are recognized as the Parakṣudra. The collection of the Ṛg is enumerated, and it is said that the Brāhmaṇa is four times as extensive. This is the measure of the Yajus and Ṛc verses, including the Śukriya, all as declared by the sage Yājñavalkya. The tradition holds that there are six thousand Ṛc verses, and then twenty-six more. Additionally, there are eleven thousand Ṛc verses, plus ten. Among these, a thousand Ṛc mantras are considered the measure. The Ṛc verses of the Atharvans are certainly five thousand. Such is what is spoken of the Āṅgirasas, and their Āraṇyaka is also described. The originators of the branches and the causes of their divisions are also remembered. The Vedic tradition of Prajapati is eternal, and these alternatives are known as Smritis. In the Dvapara ages, further divisions of the Vedas are recounted. Having imparted this knowledge to their disciples, the sages undertook austerities and withdrew to the forest. Thus, the four Vedas were established, along with their ancillary sciences—Mimamsa and the vast expanse of Nyaya. Ayurveda, Dhanurveda, and Gandharvaveda—these three great sciences—were also set forth. Know that the Brahmarshis came first, and from them arose the Devarshis. Among them are the great lineages of the Kashyapas, Vashishthas, Bhargavas, Angiras, and Atris. Because they contemplate Brahman, they are remembered as Brahmarshis. Of Pratyusha the deity, and again of Kashyapa, the divine sages are spoken. The sons of Dharma, Nara and Narayana, are also among the Devarshis. Kubera and Paulastya, and the son of Pratyusha’s branch, are included as well. From these great beings, the Vedas arise; thus, they are remembered as Devarshis. Those descended from Ikshvaku’s lineage are known as Rajarshis. Those established in Brahmaloka are remembered as pure Brahmarshis, while all those established in Indraloka are considered Rajarshis. Both the Brahmarshis and the divine Devarshis are revered. These sages possess knowledge of the past, future, and present, and are firmly established in truth and steadfastness. They are renowned for their austerity, and by them knowledge was declared even in the womb. These royal sages, endowed with virtue, and those who are divine and human kings, are all celebrated. These seven, together with seven qualities, are remembered as the seven great sages. They are enlightened, directly perceiving dharma, and are the originators of lineages. They acted with fairness and justice, through blameless causes of action. Some were householders, others wise forest dwellers, and all lived in accordance with the stages of life. Indeed, it was they who first established the arrangement of the classes and the four stages of life. They set in motion all the classes and stages of life in their entirety. In their wisdom, the father is born as a son, and the son likewise as a father, continuing the lineages unbroken. It is said that eighty-eight thousand are householders, those who have wives and perform fire-rituals, remembered as the causes of progeny. Of these, eighty-eight thousand are established in the northern region, maintaining the sacred traditions.
