This page defines the methodological framework used throughout this website for studying Nadi Astrology through the Chandra Kala Nadi tradition and its 150 Nadi Amsa reference structure. It is intended as a technical orientation to the terminology, coordinate model, sequence logic and interpretive workflow used in the individual Amsa pages.
Nadi traditions are not a single uniform system. The scope here is deliberately narrower: the Chandra Kala Nadi / 150 Nadi Amsa framework presented in this site's reference archive. Traditional terminology can vary between editions, transliterations and schools; where a name has variant spellings, the archive preserves a primary working form while identifying the variant where useful.
The working model treats each 30° zodiacal sign as a sequence of 150 Nadi Amsa positions. The nominal mean interval is therefore twelve arc-minutes per Amsa:
The coordinate is a positional index rather than a claim that every historical textual tradition expresses the divisions identically. The individual page for each Amsa records its sequence position and coordinate so that the unit can be studied reproducibly.
The archive distinguishes the sequence behavior associated with movable (Chara), fixed (Sthira) and dual (Ubhaya) signs. This distinction is important when a reader compares the same Amsa index across different signs: the numerical position alone does not provide the entire interpretive context.
The individual Amsa pages therefore identify the sequence position together with the relevant sign-class context rather than treating all twelve signs as an undifferentiated list.
The site treats a planet occupying an Amsa as an additional layer of positional information. Sun, Moon, Mars, Mercury, Jupiter, Venus, Saturn, Rahu and Ketu are examined through their relationship to the Amsa rather than through a single keyword assigned to the planet.
A technically useful reading records the planet, sign, degree, Amsa index, house context and relevant relationships before moving to interpretation. This reduces the risk of collapsing a multidimensional chart into a single generalized statement.
Nadi Amsa work is sensitive to precise longitude because a fine division is substantially smaller than a conventional zodiac sign. Consequently, birth-time accuracy and the calculation convention used by the practitioner should be documented when a reading depends on an Amsa boundary.
For research purposes, an Amsa assignment close to a boundary should be treated as a sensitivity case. The appropriate response is to record the uncertainty, examine the adjacent interval and avoid presenting a boundary-dependent inference as if it were independent of the input precision.
Each Amsa page in this archive is intended to function as a reference record. A reader should be able to identify the Amsa number, name, coordinate and interpretive framework without relying on the surrounding pages.
When comparing observations, use a consistent notation for date, birth time, location, zodiacal longitude, Amsa index and planetary placement. Separate source-based statements from later interpretive synthesis. Where a traditional claim cannot be verified against a cited edition, it should be presented as a traditional attribution rather than as an independently established fact.
Start with the Nadi Astrology homepage for the conceptual overview, then browse the 150 Nadi Amsas archive. Each Amsa page provides its own coordinate and technical discussion. Use the previous/next navigation on those pages to study the sequence continuously.

This website presents a structured study framework for a traditional astrological system. The technical language used here describes the internal logic of that framework; it should not be confused with empirical validation of astrological claims. Interpretations may differ between texts, translators and practitioners. Where uncertainty or textual variation exists, it should be retained rather than concealed by artificial precision.
