A Nadi astrologer is a practitioner of an ancient form of astrology that originates from the Tamil Nadu region in India. This practice is based on the belief that the life details of individuals are recorded on palm leaves, known as Nadi leaves, which were written by ancient sages. Each leaf contains specific information about a person's past, present, and future, and is said to be unique to each individual. During a consultation, the Nadi astrologer uses the thumbprint of the person seeking guidance to locate their corresponding leaf. The astrologer then interprets the information contained in the leaf, providing insights into various aspects of life, including career, relationships, and health. This practice is considered a spiritual and mystical approach to understanding one's destiny.
