According to law code of Manu, the
Brahmins were born from the
mouth of Brahma, the
Ksatriyas from his arms, the
Vaishy
were born from his navel, and the
Sudras were born from his legs.
In our Vedic society their duty was also accordingly i.e. the Brahminas provide
advice on spiritual matters and are engaged in worship and sacrifice, Kshatriyas
or warriors, who are likened to the arms of society and were responsible for the
protection of society. Vaishy were likened to the belly of society and their duty
was to ensure the community's prosperity through agriculture, cattle rearing and
trade. For the sudras, who are likened to the legs of society, there is labor and
service to others. Later, the Shudras took over agriculture and cattle rearing while
the Vaishyas became traders and merchants.

Etymologically, the word Vaishy derives from the root vish "to settle"
and denotes a man who "settles on the soil", i.e. a peasant. Although
Vaishy was economically strong because they controlled commerce, still they were
denied a high social status, for which they resented the upper castes. One expression
of this resentment was their support of the anti-Brahminical sects that developed
around the 6th century BC, like Buddhism and Jainism. Later, however, many influential
Vaishyas were honoured with titles like 'Nagar Seth' (chief merchant of the town)
and 'Tazimi Seth' (privileged to wear an anklet in the king's presence and in royal
durbars).
Members of trading communities originate mostly from the West Coast and from Sind
(in present-day Pakistan), are commonly known as Banias, a distortion of the Sanskrit
word vanik meaning "trader". The Vaishy group from Sindh, Kashmir, were
involved in Kesar (Saffron) business were known as Kesar-Vanik & later became
Kesarwani.
It is fact that there is no Kesarwani (Vaishya) in Kashmir today, neither there
is anything regarding Kesarwanies in Kashmir's History.
Later Vaishy divided into 7 major groups:
- Khatri
- Bohra
- Oswal
-
Kayastha
- Ahir
- Agrawal
- Bania
These groups usually do not intermarry.
