Varuna Lingam is installed facing the West and has Lord Shani (Saturn) as the dominant planet. Varuna’s vehicle is Makara – an amphibian (lives both on land and water) with the head and front legs of an antelope and the body and tail of a fish. According to mythology, Varuna is the ruler of appreciation and delight and governs the whole world. He is regarded as the god of rain and all the water bodies in the universe. Legend states that the eye of Varuna is Surya and when Surya falls in the constellation of Makara, the special event is celebrated as Makara Sankaranti during Mid-January every year. This festival is observed as Pongal in Tamil Nadu. There is a holy tank called Varuna Theertham located here. Worshipping Varun Lingam can protect you from illnesses, especially water-borne diseases. It is also believed to wash away the accumulated sins.
