How the Daśāṁśa is constructed
Each sign is divided into ten parts of 3° each. The starting point depends on whether the sign is odd or even.
- Odd signs (Aries, Gemini, Leo, Libra, Sagittarius, Aquarius)
- The ten divisions run successively from the sign itself. The daśāṁśas of Aries are Aries through Capricorn.
- Even signs (Taurus, Cancer, Virgo, Scorpio, Capricorn, Pisces)
- The ten divisions run successively from the 9th sign from it. The daśāṁśas of Taurus begin at Capricorn.
- The ten presiding deities
- Indra, Agni, Yama, Rākṣasa, Varuṇa, Vāyu, Kubera, Īśāna, Brahmā and Ananta — the rulers of the ten directions, in that order for an odd sign and reversed for an even one. Careers have a direction, and this is where the text encodes it.
The 10th house of the D-10 — the quadrant that matters
In every divisional chart, one house carries the chart's own subject with special force. In the Daśāṁśa it is the 10th house of the D-10 itself — the career within the career chart. Its occupants, its lord, and what aspects it are the first three things to look at, before anything else in the chart.
Then read the D-10 Lagna: it is the working self, the person as a professional rather than as a private individual. People whose D-10 Lagna differs sharply in nature from their Rāśi Lagna are the ones who seem like a different person at work — and they usually know it.
The 7th of the D-10 is worth a separate look for anyone considering business rather than employment, since it carries partnership and the open market. The 6th shows service, employment, subordination and daily competition — a strong 6th with a weak 10th is a career of steady employment rather than of standing.
Reading the D-10 against the birth chart
The two charts answer different questions and are meant to be read in sequence. The Rāśi 10th house shows the field: the general character of the work, the kind of activity the person is drawn into. The Daśāṁśa shows the outcome: how high it goes, whether authority is actually conferred, whether the position holds.
The productive cases are the mismatches. A strong Rāśi 10th with a weak D-10 is a person of visible professional activity whose position never quite consolidates — always working, rarely established. A weak Rāśi 10th with a strong D-10 is the reverse: an unpromising start that turns into real standing, often late and often to everyone's surprise.
For timing, pair the chart with the daśā. A period ruled by a graha that is well placed in the D-10 tends to give career movement even when the Rāśi chart is quiet, and this is one of the more reliable predictive uses of any divisional chart.
The Daśāṁśa at a glance
Every figure here is specific to this division. The Vimśopaka rows give the share of the twenty-point strength score the Daśāṁśa carries in each classical scheme — a blank means the division is not counted in that scheme at all.
| D10 | |
|---|---|
| Divisions per sign | 10 |
| Arc of one division | 3° |
| Divisional Lagna changes every | about 12 minutes |
| Vimśopaka weight · Ṣaḍvarga (6) | — |
| Vimśopaka weight · Saptavarga (7) | — |
| Vimśopaka weight · Daśavarga (10) | 1½ |
| Vimśopaka weight · Ṣoḍaśavarga (16) | ½ |
Counted in 2 of the four schemes. The more schemes a division appears in, the more the tradition treats it as load-bearing rather than specialist.
How accurate your birth time needs to be for the Daśāṁśa
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 10, so the D10 Lagna moves to a new sign about 12 minutes — and the planets near a boundary shift with it. If your recorded time is uncertain by more than that, treat the D10 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.
