Brighu Nadi and Dhruva Nadi readings from your nakshatra and pada.
This page produces two separate nadi readings from a single birth chart. The Brighu Nadi panel is keyed on the Moon's nakshatra and pada, with a second reading keyed on the nakshatra and pada of the ascendant lord, and it reports the Aadi, Madhya and Antya balance across all nine grahas.
The Dhruva Nadi panel is a different construction: it reads the 144-cell grid of every house lord in every house, adds the natural significations of the grahas, and cross-reads the navamsa positions counted from the rasi ascendant.
Both are computed from your chart rather than looked up in a manuscript. That distinction matters more here than on any other page of this site, and the next two sections are about exactly what each panel can and cannot claim.
Two things in the Brighu panel are solid. The selection rules, which are to read the Moon's nakshatra and pada and then the ascendant lord's, are structural and uncontroversial. The Aadi, Madhya and Antya classification the panel counts is the classical nakshatra attribute, the same one the Nadi koota of the marriage matching engine reads, and the two are held to agree cell for cell by a test so that the site cannot carry two versions of it.
The readings themselves are not sourced, and the app says so on the panel instead of implying otherwise. The reason is one of kind rather than of effort.
A nadi granth is by its own claim a palm-leaf record for one named individual; there is no published, checkable Brighu recension that assigns a personality, career, health, relationship, past-life and sadhana reading to each of the 108 nakshatra and pada combinations. Brighu Nadi principles names a tradition, not a locus, so that corpus can never be given a citation and no source badge is rendered over it.
The past-life field is the sharpest case in the whole app. A line such as a battlefield healer in a past life is narrative invention: no text in this site's source registry supports a past-life biography per pada, and writing one is exactly the fabricated-astrologer output this project exists not to ship. Those rows are therefore fenced in the data itself, in a list naming every hand-authored field that a reader might take as a claim about their life.
Keeping the panel and disclosing it, rather than deleting it, is a deliberate choice: the traditional material is what a reader came for, and being told clearly which parts trace to a text and which do not is more useful than being handed either a silent omission or an unmarked invention.
The dominant nadi figure is treated the same way. It is a count of the nine grahas and is reported as a count, because no source weights the nine grahas against each other for that purpose, so nothing converts the count into a verdict.
The Dhruva Nadi panel implements a scheme attributed to Satyacharya's Satya Jatakam, and the attribution was reconciled against two rival proposals rather than assumed.
BPHS chapters 12 to 23 are a real parallel, giving one chapter per bhava with verses on that bhava's lord in the twelve bhavas, but they interleave karaka, yoga and aspect rules and do not cover the grid uniformly, so they corroborate the material without being the source of a 144-cell table. Bhavartha Ratnakara was ruled out: it is 384 verses in 14 tarangas organised by lagna, yogas and dasha results, not a lord-in-house grid at all.
What the citation claims is precise. The scheme is Satya Jatakam's, since the printed editions of that text are distinguished by exactly this feature, an exhaustive bhavaphala covering all 144 combinations presented together with grahakarakatva and navamsa rules.
The wording in the app is the app's own modern synthesis and has not been matched verse by verse against any edition, because the complete Satyacharya text is not extant and the printed recension is in copyright. The panel is therefore tagged as a modern synthesis rather than as a classical citation, and the reader sees that tier on the badge.
Nadi astrology in the strict sense refers to palm-leaf manuscripts said to hold readings for named individuals, consulted by matching a thumbprint or a set of personal details to a leaf. That is a manuscript-lookup practice and it is not what happens here. Nothing on this page retrieves a leaf, and no claim is made that a reading here was written for you.
What this page does is compute. It takes the Moon's nakshatra and pada, the ascendant lord, the house lords and the navamsa from your chart, and reports the corpus rows those positions select, with the provenance of each row shown. Read that way the panels are useful and honest, and the disclosures are the part that lets you weigh them.
