Adi Perukka, also known as Aadi monsoon festival, is observed every year on the 18th day of the Tamil month of Adi. In times of yore, around this time and on this day, Cauvery River used to be in full flow, due to the South West Monsoon. The people living on its banks still celebrate this joyous occasion, of the full flow of Cauvery River.
This day is also referred to as Padinettam Perukku, Padinettu meaning 18, referring to the 18th day of the month, and Perukka, meaning to rise.
Aadi is the month for sowing, rooting, planting of seeds and vegetation, since the monsoon is at peak during this time.
This festival thus celebrates the element that is vital for agriculture, namely the life sustaining water.
This festival is celebrated in honour of Water, on the banks of rivers, lakes, water tanks and wells, and is not limited to River Kaveri alone. Nature Divinities, like Varuna and Marriamma, a goddess of rain and Kula Devata, are propitiated, in gratitude for the timely rain, which is one of the main supply of water, for the water bodies in this land.
People light lamps and float them across water bodies, as a mark of worship. The shimmering lamps in the dusk are a sight to behold, in the rippling waters.
One of the yardsticks of measuring prosperity, among many, is how a civilization or a country can harness its waters and utilize it in a sustainable manner.
More on this in our book, You Turn India and Brand Bharat.
India, over the last 5000 years, had been a prosperous civilization, primarily because, together with handling its other resources, it knew how to harness its waters for the benefit of its people.
But alas, in the last many decades, we have neglected our water bodies, including rivers, which has led them to being reduced to barrels of sand, even during monsoons.
The same story goes for the River Cauvery, which is these days muddled in disputes, between Karnataka and Tamil Nadu, for want of water.
Is it possible to get back those hoary days of abundance of water in the rivers of Tamil Nadu?
Answer lies in understanding its past!
