In Buddhism, the word "jāti" is doctrinally very important. The fully enlightened Arhat Buddhists declare upon enlightenment: "Jati has ended".
In Hinduism, "jati" is said to have the following meaning:
Jati, also spelled jat, caste, in Hindu society. The term is derived from the Sanskrit jāta, “born” or “brought into existence,” and indicates a form of existence determined by birth. In Indian philosophy, jati (genus) describes any group of things that have generic characteristics in common. Sociologically, jati has come to be used universally to indicate a caste group among Hindus.
Jāti (in Devanagari: जाति, Bengali: জাতি, Telugu:జాతి, Kannada:ಜಾತಿ, Malayalam: ജാതി, Tamil:ஜாதி, literally "birth") is a group of clans, tribes, communities, and sub-communities, and religions in India. Each Jāti typically has an association with a traditional job function or tribe. Religious beliefs (e.g. Sri Vaishnavism or Veera Shaivism) or linguistic groupings may define some Jātis. A person's surname typically reflects a community (Jāti) association: thus Gandhi = perfume seller, Dhobi = washerman, Srivastava = military scribe, etc
A few years ago, I read a blog on the internet by an Indian scholar about "varna" & "jati"; in which the scholar said the origins of the word "jati" were not clear. I commented on the blog "jati" is contained extensively in the Buddhist Pali suttas but the scholar did not reply to me. I currently am unable to locate this blog.
My question is: "Is the word &/or notion of "jāti" found in the Vedas, which pre-date the Buddha?"
