We can only begin to trace the Siddha tradition from the earliest writings found in the first century A.D. There was a country known as Kumari nadu that extended beyond what is now known as Kanyakumari, the southern most tip of India. Kumari Nadu is now lying submerged in the Indian Ocean and has been identified as Lemuria, "the sunken continent." It occupied a large area of the Indian Ocean and touched Australia in the South and Africa in the West.

According to Geology, this southern end of India, particularly Tamil Nadu, is among the oldest land mass in the world and has never been covered by the ocean.

When the earth began to erupt and change, a great Siddha named Agastyar moved to an area north of what is now Trivandrum in Kerala. This is where the civilization of the Yoga Siddhas was born.

The earliest picture of India's past is the Indus Valley civilization. This was a highly developed culture. It is observed as a civilization of pre-vedic people of ancient India that existed 8,000 to 10,000 years before the Christian era and identify it as that of the Dravidians- the world's oldest civilization. This also shows the history of Saivism (worship of the Shiva) as being the most ancient living faith in the world, first developed by the Dravidians in southern India.
