Nadi astrology ('நாடி ஜோதிடம்' in Tamil), (nāḍi jyotiṣa) is a form of Hindu astrology practiced around the temple. It is based on the belief that the past, present and the future lives of all humans were foreseen by Hindu sages in ancient time. The texts are mainly written in Vatteluttu, which is an ancient Tamil script. There are different schools of thought as to the author of these leaves.
