The Saaraswat People: The Saaraswat people got their name from the Saraswati river along the banks of which they were originally settled. The Saraswati river is now seen only as a subterranean shadow in the pictures of the state of Punjab taken from the satellites.
There occurred a 12-year famine in about 5000 B.C. (period mentioned needs authentication) in Punjab which caused the river Saraswati to dry up and vanish. This famine was enough to kill a large number of people in the area due to starvation. A lot of information which the people of the time kept memorized was lost by the death of the masses. The written information on papyrus was either left unattended to be lost to nature, or carried along to the destinations by the escapees.
A large number of able bodied survivors escaped to the east and came to live along the banks of the river Ganga and its tributaries. Many families settled down in the new location but a good percentage of the new generations returned to Punjab in later years.
After many many years the migrant Saaraswats in Gangetic plains gained name and fame in the new colonies as wise men. They had known ways and means to appease gods and to consign the souls to the heaven after death. They performed elaborate fire sacrifices and dictated the correct procedures for the same. They were in demand in all different kingdoms and courts. They were identified by their family names such as Bhrigu, Angirasa,Vsishta, Kashyapa, Agastya and Atri. All those men through the ages born to Bhrigus for example would be known by the same name. They were placed in the highest class among men and called the Brahman(s). The Saaraswat Brahman had other rivals such as the Kanyakubja, Maithila, Gauda and Utkal Brahmans who were either original residents or off-shoots of the new settlers.
Meanwhile in the peninsular portion of the land known as Bhaarath (later referred to as India) below the Vindhya mountain ranges, there were Brahman families bearing names such as Dravida, Tailang, Karnaata, Madhyadesi, and Gurjara. Thus there were in the course of time, about ten different primary divisions constructed among the Brahmans of Bhaarath.
The Story of Lord Parasurama: The history of Saaraswat Brahmans is incomplete if Lord Parasurama is not taken into account. It is said that Parasurama was the godly administrator of the west-coast of India so much so that he had thrown his pickaxe across the sea to extend the land upto the line along which his axe fell. Therefore the land consisting of Konkan, Goa, coast of Karnataka, and Kerala is known as Parasurama territory.
To give a more rational explanation to this improbable legend, the discovery of land beyond the Western Ghats and conquering it by Parasurama led to the theory of the pickaxe. This land was inaccessible for people of Gujarat, Madhyadesha, Karnaata, Tailang and Dravida and hence it was a new discovery when Lord Parasurama rode across the Western Ghat mountains and established his control over it.
The Story of Brahman settlements in Goa: Once Parasurama established himself as the ruler of Konkan, Goa and other coastal territories, he experienced the lack of Brahmans in the region. He arranged to bring in Brahmans from the Tri-hotra region of northern Gangetic plains. The region in the northern Gangetic belt (consisting roughly the present districts of Champaran, Saran, Darbhanga and Muzaffarpur) was known as Tri-hotra which later shortened to Tirhut. The first batch of Brahmans were settled in Goa.
Their family names or Gothra(s) were the following: Bhaaradwaaja, Kausika (also known as Kaumsa), Vatsa, Kaundinya, Kashyapa, Vasishta, Jamadagni, Vishwaamitra, Gautama and Atri. More Brahmans from other areas including the Bengal came to Goa on invitation of the rulers following Parasurama. These families were belonging to Sankha Pingala Kamsa, Garghya, Angirasa, Nair dhruva, Dhananjaya, Mudgala, Vainya, Harsha, Hariha, Shandilya and Sankhyana.Family Deities or Kula Devata.
The Brahmanas brought the idols of gods along when they arrived in Goa. Their gods were Mangesh, Mahadeva, Mahalakshmi, Mhalasa, Shanta Durga, Nagesh and Sapta Kotishwara. Each person knows and remembers the name of his family deity since during various rituals the family deity is first invoked and thereafter the god that is to be worshipped. Also it is a practice for the newly married Saaraswat couple to visit the temple of their family deity in Goa immediately after a marriage. The temples of all the family deities of Saraswats are located in and around Goa.
