Roots of Naadi Astrology is a practical study material on different Naadi systems selected from classical and modern works. The author has experimented on
applicability of the rules from these Naadi systems. In this monumental work he restricts himself in presenting the most useful principles and avoids unnecessary texts. He puts his logical observations while presenting the topics. He covers the following great works in this volume:

1. Dhruva Naadi ( Satya Jataka)
2. Universally applicable rules from Chandra Kala Naadi
3. Bhrighu Nandi Naadi

From Modern works he selects applicable Naadi principles of
1. Stellar system that uses Component of Panchanga

2. Stellar system that uses Jeeva and Sareera principle

3. Stellar system that uses Dasha Bhukti divisions in zodiac

Throughout the book he uses an example horoscope to establish the applicability of the rules in different Naadi systems. There are various types of Naadi granthas. Chandra Kala Naadi, Dhruva Naadi, Bhrigu Naadi, Nandi Naadi, Saptarishi Naadi, Vidyamadhaveeyam, Kakabhujandar Naadi, Guru Naadi, Buddha Naadi, Surya Naadi, Kapila Naadi, Vashistha Naadi, Shukra Naadi, Saptarishi Naadi and Pushya Naadi. Some of them are in different libraries or with traditional families in south India and North India.

These Naadi systems have five different methods of giving readings. One set of granthas relates reading based on horoscopes with divisional reference points as with Dhruva Naadi, Chandra kala Naadi. Another set of Naadi goes with the stellar division which has some basis in Vidya Madhavaveeyam. Yet another set of reading is based on signification of planets with or without relating to Dasha bhukti like Nandi Naadi and Bhrigu Naadi. One more set is called Mantra Naadi which has some occult interference in reading through the palm leaves.

Very rarely I have come across a Naadi reader having this mantra Naadi. However, some Naadi palm leaves and old scripts are available in the south Indian and North Indian libraries. Most of them are in Sanskrit, Tamil, Telugu and Kannada languages. The 5th one is Naadi reading based on thumb impression index and identifying the palm leaf having the whole life reading including the names of relatives. This has become famous across the world over two decades.
