01Overview
02The angle everyone else can see
The tenth house is the top of the chart and the most exposed department in it — the work, the authority attached to it, and the standing that follows from being seen to do something. Unusually, it is both a kendra and an upachaya, so it is an angle that also accumulates rather than reporting all at once. Mangala standing there is force placed in the department that exists to be acted in.
03The shape this placement usually takes
04The one chart where everything lines up
A Cancer ascendant puts Aries in the tenth, and three separate things become true at once: Mars takes digbala there, it sits in its own sign inside a kendra which satisfies Ruchaka yoga, and for a Cancer lagna it owns a kendra and a trikona and is therefore the yogakaraka. There is no stronger ordinary configuration for Mangala anywhere in the twelve houses. It is worth naming precisely because the rest of this grid is spent explaining that a house number settles nothing — occasionally the house, the sign and the lordship all point the same way.
05Direction used, and direction wasted
| The strength converts | The strength stays potential | |
|---|---|---|
| The 10th sign | Capricorn (exalted), Aries or Scorpio (own) | Cancer (debilitated) — a Libra lagna |
| The 10th lord | Well placed, in an angle or a trine | Weak, combust, or in a dusthana |
| The dashamsha (D10) | Mars holds its condition in the D10 | Thins there — the promise does not carry across |
| Saturn | In contact — speed acquires staying power | Absent — a career of starts |
| The Sun | Sound — authority has somewhere to sit | Weak — force without a position to use it from |
06What digbala actually measures
Directional strength is usually stated as a house fact — Mars and the Sun take it in the tenth — but in the shadbala system it is computed from longitude, scoring highest at one point and falling to nothing at the opposite one. Under that computation a Mars listed in the tenth house can hold only a fraction of the available dig bala if it sits far from the relevant point, and the answer also shifts depending on whether whole-sign or bhava chalit house division is used. Practitioners split between quoting the house rule and running the arithmetic, and the two do not always agree about the same chart.
