Nadi astrology is an ancient form of astrology practiced in India, particularly in the southern regions. It is based on the belief that the life details of every individual are recorded on palm leaves by ancient sages, known as Rishis. These leaves contain predictions about a person's past, present, and future, which can be accessed through a process of thumb impression analysis. The practice involves a reader, often referred to as a Nadi astrologer, who interprets the inscriptions on the palm leaves. Clients provide their thumbprint, which helps the astrologer locate the corresponding leaf. This unique approach aims to offer insights into one's life path, relationships, and spiritual journey.
