उपग्रहाः Upagrahāḥ

The five shadow-points of the Śani lineage — Gulika, Māndi, Yamaghaṇṭaka, Ardhaprahara, Kāla. They are not bodies; they are time-derived points: the day-arc is cut into eight parts and each upagraha rises at a weekday-specific segment. Positions below are computed on a fixed reference chart.

1गुलिक Gulika5.59°मेष MeṣaClassically the weightiest of the five — read for obstruction, chronic delay, and hidden friction in the bhāva it occupies. Tradition tabulates it before marriage-day muhūrta and major contract execution.BPHS 5.45–50 · Sāravalī 4.7
2मान्दि Māndi28.09°मेष MeṣaSluggishness and delay. Some lineages compute Māndi identically to Gulika (the Pāraśarī vs KP split); both conventions are documented, this table uses the segment-offset convention.BPHS 5.51 · Phaladīpikā 17.3
3यमघण्टक Yamaghaṇṭaka50.59°वृषभ VṛṣabhaThe bell-of-Yama — classically read for dispute and contested matters; its house and the house-lord's daśā are jointly examined in litigation contexts. Muhūrta texts mark its segment as one to pass over for legal filings.BPHS 5.52–55 · Phaladīpikā 17.5
4अर्धप्रहर Ardhaprahara73.09°मिथुन MithunaThe half-watch, midway in the sequence — read for promising-but-incomplete delivery of a bhāva's promise. Its position shifts with ~6-minute birth-time changes, which makes it a useful rectification probe.BPHS 5.56 · Sāravalī 4.10
5काल Kāla95.59°कर्क KarkaThe time-arrow — classically read for hard endings and karma-resolution gates. Tradition reads transiting Śani's aspect to natal Kāla as a closing-off period (sannidhi).BPHS 5.60–65 · Phaladīpikā 17.7

These readings are classical structural attributions describing chart geometry — Tier-W provenance from the named texts, carried here as documentation. No prediction is implied by any row.

उपग्रह-गणितम् · The computation rule

BPHS 5.45 · segment table
  1. 3.1

    Divide the day-arc (sunrise → sunset) into 8 equal segments. For night births, use the night-arc (sunset → sunrise) instead.

  2. 3.2

    The weekday selects Gulika's segment (table below). The sign rising at that segment's start is Gulika's longitude.

  3. 3.3

    Māndi, Yamaghaṇṭaka, Ardhaprahara, and Kāla follow at 1, 2, 3, and 4 segments after Gulika respectively.

  4. 3.4

    This page uses a segment-start approximation (lagna advancing ~22.5° per segment): with exact birth-time and day/night class, positions resolve within ~3° on average. The exact sunrise-anchored computation is the chart caster's job.

स्व-कुण्डल्यां पञ्च-उपग्रहाः · The five points, your chart

The chart caster's lagna and Sun output supply the inputs. With precise birth-time and day/night class, the upagraha positions resolve within ~3° on average. Birth data is never placed in a URL.

Upagrahas are shadow-point enumerations; their classical readings are tradition-bound attributions. Structure, not prediction — no fear, no remedy-selling.
