Agasthiyar Maharishi, one of the 18 revered Siddhars, studied human destiny by analyzing thumb impressions—categorized into top, middle, and bottom lines—to reveal life circumstances. Following the prescribed remedies can help mitigate hardships.

Nadi inscriptions originated nearly 5000 years ago, recorded by the Sapta Rishis and Siddhars through divine insight. Initially preserved in the Saraswathi Mahal Library, many manuscripts were later collected by astrologer families from South India.

Vaitheeswaran Koil, near Chidambaram, Tamil Nadu, is the principal center for Nadi astrology. The town is spiritually significant, as Lord Shiva is believed to manifest as a divine healer for devotees.

Thumb impressions are classified into 108 types, guiding the search for corresponding palm leaves. The identification speed varies depending on the clarity of the thumbprint.

Nadi astrology transcends regions and religions, though only about 60% of seekers locate their leaves due to damage or loss. It connects thumbprints, palm lines, surroundings, and facial structure to reveal karmic paths and suggest remedies for a harmonious life.
