How the Bhāṁśa is constructed
Each sign is divided into twenty-seven parts of 1°6'40" each — one for each nakṣatra.
- The counting rule
- The distribution begins from the movable sign of the group the sign belongs to. Aries, Leo and Sagittarius count from Aries; Taurus, Virgo and Capricorn from Cancer; Gemini, Libra and Aquarius from Libra; Cancer, Scorpio and Pisces from Capricorn.
- The twenty-seven presiding deities
- The nakṣatra deities themselves rule the divisions — Dasra, Yama, Agni, Brahmā, Candra, Īśa, Aditi, Jīva, Ahi, Pitara and the rest, in order for an odd sign and reversed for an even one. This is the only division whose lords are the nakṣatra powers rather than planets or signs.
- Fine resolution
- Each division is just over one degree wide, which makes the D-27 quite sensitive to birth time — less so than the D-60, more so than the D-9.
What "underlying strength" actually means
This is not physical strength and it is not the six-fold Ṣaḍbala. It is closer to constitution: the reserves a person has, what they can sustain, and the specific point at which sustained pressure produces failure.
The tradition treats the D-27 as showing the subconscious side of strength — the tendencies a person is not choosing and often not aware of, which nevertheless decide how much they can take. Two people with equally capable birth charts can differ entirely here, and the difference emerges only under prolonged strain.
Because the divisions are ruled by the nakṣatra deities, the chart also carries a distinctly characterological flavour. A graha in the Bhāṁśa of a fierce nakṣatra behaves differently under pressure than the same graha in a gentle one — the placement describes the manner of endurance, not only its quantity.
How to read the D-27
Read the D-27 Lagna and its lord as the constitution itself, and the 6th house as the point of failure — where illness, depletion and breakdown enter. The 8th shows what a person can survive and what transforms them; the 12th shows what quietly drains them without their noticing.
Look particularly for grahas that are strong in the Rāśi and weak in the D-27. That combination describes capability without reserves: someone who performs impressively and cannot sustain it, whose collapse is a surprise to everyone including themselves.
Use it as a supporting chart rather than a primary one. The D-27 rarely answers a question by itself, but it very often explains why an otherwise promising chart does not deliver.
The Bhāṁśa at a glance
Every figure here is specific to this division. The Vimśopaka rows give the share of the twenty-point strength score the Bhāṁśa carries in each classical scheme — a blank means the division is not counted in that scheme at all.
| D27 | |
|---|---|
| Divisions per sign | 27 |
| Arc of one division | 1°06'40" |
| Divisional Lagna changes every | about 4 minutes |
| Vimśopaka weight · Ṣaḍvarga (6) | — |
| Vimśopaka weight · Saptavarga (7) | — |
| Vimśopaka weight · Daśavarga (10) | — |
| Vimśopaka weight · Ṣoḍaśavarga (16) | ½ |
Counted only in the full sixteen-division scheme. That is a statement about how the tradition ranks it — real, but supporting rather than decisive.
How accurate your birth time needs to be for the Bhāṁśa
The Rāśi Lagna moves through a whole sign in roughly two hours, which is why the birth chart tolerates an approximate time. This division cuts each sign into 27, so the D27 Lagna moves to a new sign about 4 minutes — and the planets near a boundary shift with it. If your recorded time is uncertain by more than that, treat the D27 Lagna and any house-based conclusion drawn from it as provisional, and rectify the time against dated life events before relying on it. Sign placements of the slower grahas stay stable much longer than the Lagna does.
How this is computed
Positions come from an astronomical ephemeris, converted to the sidereal zodiac on the Lahiri (Citrapakṣa) ayanāṁśa and computed by our own Parāśara engine — no pre-written results, and no language model anywhere near a number. Where the classical texts disagree, this page names the convention we follow instead of quietly picking one.
