of 150. Thus, there are 450 distinctive names and numbers in the full zodiac. Nādi texts use this concept of Nādi as the basic unit for prediction. That is why they are called "Nādi amshas". Chandra Kalā Nadi, which is also known as Deva Keralam, was published by Sagar Publications in 1992, edited, and translated into English by R Santhanam. It is a compilation of over 82 hundred verses by Achyut of Kerala. That is why it is called "Deva Keralam". But its original kernel was Chandra Kalā Nādi, which has not been preserved as a separate text. Deva Keralam has borrowed many non-Nādi concepts also to make the book fuller, but it preserves the gist of Nādi astrology. However, there are many different trends in Nādi Astrology that are not present in Deva Keralam. There are Nādi texts named after planets, such as Guru Nādi or Shukra Nādi, and there are voluminous unpublished texts like Dhruva Nādi. The palm leaves in Tamil Nādu temples use a style different from that of Deva Keralam, and the Tamil method of Nādi Astrology is paralleled by Bhrigu Samhitā in north India, which has been published in part, but many spurious publications in the name of Bhrigu Samhitā have also appeared in the market. The basic methodology of these Nādi or Samhitā texts has never been described in these texts, hence astrologers can predict only what they already possess, and are dumbfounded when they do not possess the required leaf about some particular person. The most fundamental trait of Nādi texts is Nādi, which is a sum total of all divisions of a sign caused by sixteen divisional charts (shodasha Vargas) described in texts like BPHS (Brihat Parāshara Horā Shāstra). 135 divisions out of a total of 285 are repeated in other divisions; hence there are exactly 150 distinctive divisions of a sign. But these divisions are unequal; largest division being of half a degree, and the smallest division is 36th part of a degree. Another school of thought assumes that all 150 divisions are equal; the value being 12 minutes (arc) in length. When predictions are based on Nādis in which ascendant and planets are placed; it means the combined results of all sixteen divisional charts are being told. Hence, Nādi Astrology is the most detailed and accurate method. But it requires highly precise birth time, and it also requires knowledge of
