Jataka texts of Jyotish
Jataka texts are the classical works on the interpretation of the birth chart, and Sripati's Jataka Paddhati is among the well-known examples, commonly dated to the 11th century CE.
What it is
Such texts organise the reading by the houses, the grahas and their combinations, and they often give examples. The Jataka Paddhati is one of the works read in the Jataka tradition alongside the Parashari texts.
How it is worked out or read
The site does not quote these works for specific claims, since the editions and chapters have not been verified. The general method is described in the Parashari articles.

Sripati
Sripati was an astronomer and astrologer of the eleventh century CE, usually placed around 1019 to 1066. He wrote in several branches of Jyotish: the Siddhanta Shekhara on astronomy, the Dhikotida karana for calendar computation, the Jyotisha Ratnamala on muhurta, and the Sripati Paddhati on horoscopy. The Sripati Paddhati is the work most often met by students of chart reading today.
Sripati's name is also attached to a method of house division, sometimes called Sripati bhava, in which each quadrant between the Lagna, the tenth-house cusp and their opposites is divided into three. This gives unequal houses when the quadrants are unequal, and it is used in some traditional calculations of bhava chalit charts.
The family of jataka texts
Jataka texts are the texts on natal astrology, the reading of a birth chart. Alongside the Brihat Parashara Hora Shastra, the most widely studied include Varahamihira's Brihat Jataka and its shorter companion Laghu Jataka, the Hora Sara attributed to Prithuyasas, Kalyanavarma's Saravali, Mantreshwara's Phaladeepika, Vaidyanatha's Jataka Parijata and Venkatesha's Sarvartha Chintamani. Each has its own emphasis and style, and their dates range across many centuries.
Many of these texts quote or build on earlier ones, so a student will find the same yoga or rule appearing in several of them with small variations.
How the texts differ
The Brihat Jataka is terse and dense, written for readers who already know the basics. The Saravali is much longer and more explanatory, and is valued for its wide coverage of planetary combinations. The Phaladeepika is systematic and practical, and the Jataka Parijata collects material from many earlier sources. The Sripati Paddhati focuses on method, especially the calculation of house strength and related techniques. Knowing these differences helps a reader choose which text to consult for a given question.
Reading the texts today
Most readers meet these texts through translations with commentary, and the quality of translations varies. When a modern book quotes a classical rule, it helps to know which text it comes from and, where possible, to check the verse in a reliable edition. Different editions sometimes number verses differently, and some popular rules attributed to classical texts cannot be found in them at all. A careful reader keeps a note of the text, chapter and verse for any rule they rely on.
Where this site fits
The articles on this site name the classical text where a definition comes from, and note where the texts disagree. The calculators implement the commonly used Parashari methods, and the yoga detection on the chart page follows definitions found in standard texts. Readers who want to go further are encouraged to read the texts themselves in good translations.
