Introduction
Iyers, also spelled as Ayyar, Aiyar, Ayer, or Aiyer, are described as an ethnoreligious community within the Tamil Brahmin population. The majority of Iyers follow the Advaita philosophy established by Adi Shankara and adhere to the Smarta tradition. This distinguishes them from the Iyengar community, who follow Sri Vaishnavism. Together, Iyers and Iyengars are collectively referred to as Tamil Brahmins and are classified under the Pancha Dravida Brahmana grouping in India. In addition to commonly using “Iyer” or “Aiyar” as a surname, members of the community also frequently adopt other surnames such as Sastri or Bhattar.

Iyer Brahmin belongs to the largest Brahmin community of South India. Tamil Nadu is their home state, though there is a large number of Iyers in Kerala as well. They are mostly engaged in administration. Slow to change, the Iyers still cherish their age-old Brahminical customs and practices. This community has made a great contribution to the literary and cultural heritage of South India.
Etymology of Iyer Brahmin
The term “Iyer” carries multiple meanings in Tamil and other Dravidian languages, often denoting a person of respect or authority. According to the Dravidian Etymological Dictionary, the word encompasses meanings such as father, sage, priest, teacher, Brahman, superior person, master, or king. It is also associated with cognates like “tamayan,” meaning elder brother, and “ai,” which conveys titles such as lord, master, husband, king, guru, priest, teacher, or father.
It is commonly believed that Iyer is the plural form of
"Iye" which evolved from the word "Arya". Linguistic
interpretations suggest that related forms such as “Ayya” and “Ayira” or
“Ayyira” evolved as Prakrit
adaptations of the Sanskrit
term Arya, which signifies “noble.” These days, however, the members of this
sect have begun to give up the caste name of Iyer. Earlier, a typical Iyer name
had four constituents which included the name of the birth place or place of
origin of the family, the initial letter of
the father’s name, and the “given” name and the caste name.
Origin of Iyers
Iyers believe that they are descended from the ancient
rishis. Each family belongs to a gotra named after a rishi. Traditionally they
adopt one of the following appellations: Iyer, Sastri, Sarma, Dikshitar,
Ghanapathigal, Sroutigal and Rao. They are divided into subjects, each denoting
either a particular origin, mode of worship or social practice, which are
Vathima, Ashtasahasram, Dikshitar, Sholiar (or Chozhiar), Mukkani, Kaniyalar,
Sankethi, Prathamasaki and Gurukkal.
Society of Iyer Brahmin
The Iyers like other Brahmins, may follow any of the three Vedas, namely Rig, Yajur
or Sama. The followers of the three Vedas are
regarded as equals and can inter-marry, the wife adopting the
Veda of the husband. There are a number of gotras into which all Brahmins are
divided, such as those of Atri, Bhrigu, Rutsa, Vasishtha,
Gautama,
Kashyapa,
Bharadwaja,
Kaundinya and Angirasa.
In their ceremonial rites, they are guided either by the laws (sutras) laid
down by Apastamba or Bodhayana. Iyers are generally
vegetarian. Some abjure onion and garlic on the grounds that they activate
certain base senses.
Sub-Sect of Iyer Brahmin
Iyers are further divided into various sub-sects based on cultural and regional differences. The sub-sects are Vadama, Brahacharnam or Brahatcharanam, Vathima, Sholiyar or Chozhiar, Ashtasahasram, Mukkani, Gurukkal, Kaniyalar and Prathamasaki. Each sub-sects claim to be superior to the rest.
Culture of Iyer Brahmin
Iyers generally lead orthodox lives and adhere steadfastly
to their customs and traditions. While performing Sandhya or while offering a salute
to an elder, an Iyer mentions his lineage or gotra and
his law giver (Apastamba or Bodhayana) in addition to his name. The lifestyle of Iyer Brahmin is
quite disciplined. They follow religious rites according
to the rules and the social customs. These are the foundation stones for the
Iyer community.

Although they may appear to be Shaivas,
Iyers are Smratas i.e. followers of the Smritis. Smarta Tradition is a liberal form of Hinduism whose
worship contains 5 key deities, namely Shiva, Vishnu,
Shakti, Surya
and Ganesha.
Most of them are followers of Sankara and Six-Fold Faith or
"Shanmata". Another distinction is that the Iyers wear the leaves of
both the Tulsi plant, sacred to Vishnu and the bilva plant,
sacred to Lord Shiva, on their head.
Like members of other Brahmin communities, Iyers must observe the 16 samskaras (literally meaning refinement but in practice also connoting consecration or sanctification). Some of the important ones are as follows:
Garbhadhanam is performed at the time of the nuptial ceremony and sanctifies the procreative act; ‘pumsavanam’ and ‘siman-tonnayanam’ (parting of the hair) ceremonies protect the mother and the child she is carrying and are performed during the first pregnancy.
Jatakarma
is performed at birth, the child being fed with gold, honey and ghee. Namkaran ceremony
(name-giving ceremony) takes place when the child is 11 days old. The rite of ‘annaprasanam’
is the feeding of rice or solid food to the child for the first time. Upanayan must be
conducted in the fifth or eighth year although the Iyers are not strict about
keeping this rule.
Religious Duties of Iyer Brahmin
An Iyer is enjoined to lead a disciplined life. He must rise at the hour of Brahma i.e. 3a.m., make his ablutions and recite the Gayatri Mantra at least 108 times. The Brahmachari (believed to be aged below 25 years) performs the samidadhanam and the grihastha (aged between 25 to 50) perform upasana. In both these rites, offerings are made to the sacred fire. This is followed by what is called Shiva puja, though all the deities are worshipped at this time. Along with a Shiva linga, it is important to have a saligram, which is a Vaishnava symbol, in the household. The various images are washed with water and milk as the performer of the puja chants Vedic hymns, this ‘abhisheka’ being followed by the offering of flowers.
The devout Iyer makes it a point to read the Ramayana or the Bhagavad Gita. Iyer make recites the thousand names of Vishnu at dusk, followed by stotras (praises) addressed to Ganapati his guru, Saraswati, Lakshmi, Rama, Krishna, Hanuman, Subramanya and other Gods and Goddesses. He may also read the Devi Mahatmayan. He performs the sandhya at dawn and dusk and the madhayhnikam during midday. The Gayatri japa is the most important part of these daily rites. An Iyer who does not chant the Gayatri is not fit to perform any other ceremony.
Before the commencement of any rite, Iyers invoke Ganapati, Vishnu and Paramesvara (Shiva) but in their ‘sankalpa’ they declare that they are performing the rite to please Paramesvara (the Supreme God). Initiation by a guru is necessary before certain deities can be worshipped. There is a ‘mulamantra’ (root mantra) pertaining to Shiva and to Vasudeva or Narayana into which Iyers are usually initiated.
There is a Shaiva tradition among Iyer community as they are
worshipers of Rudra, a form of Lord Shiva. But the worship of Vishnu and Vaishnava deities,
such as, Rama, Krishna and Hanuman, has a place of equal importance in their
life. When an Iyer male performs his sandhya, he invokes the various names of
Vishnu.
Marriage in Iyer Community
An Iyers marriage is a mixture of Vedic ritual and Tamil custom.
First, horoscopes
are matched. Then an auspicious day is fixed by the priests
for the marriage.
The bridegroom is taken in procession to the bride`s place and is welcomed with
music and the betrothal ceremony is then held. The `vrntam` is conducted on the
morning of the marriage day.

The bridegroom goes on a short symbolic “pilgrimage,” possibly to Kasi carrying umbrella, walking stick and a coconut. The bride’s father goes to meet him and persuades him to return and marry his daughter. Some non-Brahmin communities also enact this prelude.
The couple sits before the holy fire and the priests chant
Vedic hymns. The bride’s father washes the bridegroom’s feet with milk and
water and affirms that he is giving away his daughter in marriage. Then follows
the ‘panigrahanam’ or the clasping of each other’s hands by the couple. This is
one of the most important rites. Saptapadi or taking
seven steps together round the sacred fire, is of equal significance. Among the
non-Vedic rites observed is the tying of the tali by the bridegroom round the
bride’s neck.
Festivals in Iyer Community
The festivals
of the Iyers are numerous, most of them being common to other Hindu communities. They
are Upakarma, Diwali
(festival of lights), Bhogi Pandigal, Pongal, Taipusam, Mahashivaratri, Ramanavami,
Janamashtami,
Vmayaka Chaturthi and Navaratri.
Iyers observe a number of vratams (vows). One is to propitiate Varalakshmi.
Rishipanchami is observed by elderly women. Fasting
is common with the devout. An important festival, exclusive to Brahmins of
South India, is the Avani Avittam festival, a significant event, primarily
observed by Tamil Brahmin men for renewing their sacred thread, which is the
"Yajnopavita" or "Poonal".
Evolution of Iyer Community
For centuries the Iyers preserved the Hindu way of life, orthodoxy and Brahminic ritual and though they took to modern education, they did not become westernised. But in recent decades they have spearheaded social reform and played a great role in the struggle for freedom. Their contribution to music is immense. They have produced some of India`s greatest lawyers, administrators, statesmen and scientists and others who have kept alive the religious and cultural heritage of India.
The Iyer community has produced outstanding administrators
and politicians, such as, C.P. Ramaswami Aiyar (1879-1966); scholars such as U.V.
Swaminatha Iyer (1855-1942) who brought to light many palm-leaf manuscripts
to enrich Tamil
literature. The famous scientist C.V. Raman
(1888-1976) who was the first Indian to win the Nobel Prize in a science
subject (physics) was also an Iyer. Many legal luminaries; outstanding poets
like the revolutionary poet Subrahmanya Bharati,
who gave a new direction to Tamil literature by taking the language to the
masses. Famous dancers and musicians from Iyer community are Rukmini Devi
Arundale, Muthuswami
Dikshitar and Syama
Sastri. The defense services have also attracted a large number of Iyer
young men.
