Many centuries ago, some of the Great Sages of India who could foresee the future of many individuals, wrote the same on palm leaves (known as Nadi) for their welfare of by spending their whole lives in order to ease their lives. Perhaps, this was the effort extended by them to preserve “Dharma” during the Kalyuga. However, they intended to help the humanity to be on the right track by spiritual wisdom. Lord Shiva bestowed exclusive clairvoyance powers on some of these sages on being pleased with their devotion and prayers. These sages created the records on palm leaves associated with an individual's past, present and future.
