034 verses, the largest portion, on laws for and expected virtues of Brahmins. It asserts, for example,
A well disciplined Brahmin, although he knows just the Savitri verse, is far better than an undisciplined one who eats all types of food and deals in all types of merchandise though he may know all three Vedas.
John Bussanich states that the ethical precepts set for Brahmins, in ancient Indian texts, are similar to Greek virtue-ethics, that "Manu's dharmic Brahmin can be compared to Aristotle's man of practical wisdom", and that "the virtuous Brahmin is not unlike the Platonic-Aristotelian philosopher" with the difference that the latter was not sacerdotal.
According to Abraham Eraly, "Brahmin as a varna hardly had any presence in historical records before the Gupta Empire era" (3rd century to 6th century CE), when Buddhism dominated the land. "No Brahmin, no sacrifice, no ritualistic act of any kind ever, even once, is referred to" in any Indian texts between third century BCE and the late first century CE and also states that " The absence of literary and material evidence, however, doesnot mean that Brahmanical culture didnot exist at that time, but only that it had no elite patronage and was largely confined to rural folk, and therefore gone unrecorded in the history". Their role as priests and repository of sacred knowledge, as well as their importance in the practice of Vedic Shrauta rituals grew during the Gupta Empire era and thereafter. However, the knowledge about actual history of Brahmins or other varnas of Hinduism in and after 1st-millennium is fragmentary and preliminary, with little that is from verifiable records or archeological evidence, and much that is constructed from a-historical Sanskrit works and fiction. Michael Witzel writes,
Toward a history of the Brahmins: Current research in the area is fragmentary. The state of our knowledge of this fundamental subject is preliminary, at best. Most Sanksrit works are a-historic or, at least, not especially interested in presenting a chronological account of India's history. When we actually encounter history, such as in Rajatarangini or in the Gopalavamsavali of Nepal, the texts do not deal with brahmins in great detail.
The Gautama Dharmasutra states in verse 10.3 that it is obligatory on a Brahmin to learn and teach the Vedas. Chapter 10 of the text, according to Olivelle translation, states that he may impart Vedic instructions to a teacher, relative, friend, elder, anyone who offers exchange of knowledge he wants, or anyone who pays for such education. The Chapter 10 adds that a Brahmin may also engage in agriculture, trade, lend money on interest, while Chapter 7 states that a Brahmin may engage in the occupation of a warrior in the times of adversity. Typically, asserts Gautama Dharmasutra, a Brahmin should accept any occupation to sustain himself but avoid the occupations of a Shudra, but if his life is at stake a Brahmin may sustain himself by accepting occupations of a Shudra. The text forbids a Brahmin from engaging in the trade of animals for slaughter, meat, medicines and milk products even in the times of adversity.
The Apastamba Dharmasutra asserts in verse 1.20.10 that trade is generally not sanctioned for Brahmins, but in the times of adversity he may do so. The chapter 1.20 of Apastamba, states Olivelle, forbids the trade of the following under any circumstances: human beings, meat, skins, weapons, barren cows, sesame seeds, pepper, and merits.
The 1st millennium CE Dharmasastras, that followed the Dharmasutras contain similar recommendations on occupations for a Brahmin, both in prosperous or normal times, and in the times of adversity. The widely studied Manusmriti, for example, states:
Except during a time of adversity, a Brahmin ought to sustain himself by following a livelihood that causes little or no harm to creatures. He should gather wealth just sufficient for his subsistence through irreproachable activities that are specific to him, without fatiguing his body. – 4.2–4.3 He must never follow a worldly occupation for the sake of
