Overview

Vedic astrology schools are better compared through named methods than through a label alone. Start with the calculation settings, then the rule being used, and finally the edition or teacher that explains it.

At a glance

Start here
A school name is not a complete calculation specification.
Method comparison
Separate graha aspects, rasi aspects, karaka ranking and dasha rules.
Text identity
Record title, editor or translator, volume and passage.
Evidence limit
Traditional provenance and reproducible arithmetic do not establish predictive accuracy.

Which page should you read first?

Use Parashari vs Jaimini when two readings differ in their aspect, karaka or timing method. Use KP and Nadi variants when a report introduces star-lords, sub-lords or a named Nadi approach. These are method questions; changing the cover label cannot resolve them.

Use the BPHS page to identify a particular copy of Brihat Parashara Hora Shastra. Use classical texts and source criticism to judge whether a passage supports a claim. Rao's preface advocates integrating techniques, but his position should not be mistaken for a universal definition of every school.

A school label does not decide the karaka scheme

For a deliberately simplified ranking exercise, let the Sun be at 24° within its sign and every other ordinary planet below 24°. In a seven-planet scheme without Rahu, the Sun ranks first. In the eight-body rule described by Rao, Rahu at 5° is measured as 30° − 5° = 25° and ranks above the Sun.

The useful record is therefore not just “Jaimini.” Write the included bodies, the Rahu transformation and the tie rule next to the result. This example compares algorithms only; neither first place nor the name Atmakaraka demonstrates a person's spiritual worth.

Build a small, checkable reading notebook

For each technique, keep one row with inputs, chosen rule, source locator and computed output. Leave interpretation in another column. When a result changes, alter one setting at a time so that an ayanamsa change is not confused with a change of aspect system.

Begin with one worked rule rather than choosing a supposedly best school. An identifiable teacher or book can explain its own practice, while a publisher listing can identify an edition; neither alone proves historical priority or reliable life prediction. Unlocated quotations remain questions to investigate, not facts to publish.
