Mars (Mangala) — the commander of the chart
Mangala is the chart's supply of heat that does something: the courage to start, the strength to push through, the edge that separates one thing from another. The classical texts cast Mars as the army's commander among the grahas — not the king, but the one the king sends when talking is over. It rules both Aries, where its fire initiates, and Scorpio, where the same fire holds under pressure. Its placement shows where you fight, what for, and how cleanly. Mars is also the graha examined in Manglik (Kuja dosha) matching — less a curse than a temperament to pair wisely.
As karaka — significator — Mars stands for courage, physical energy, younger siblings, land and property, discipline in action, and the ability to cut. Its Vimshottari mahadasha runs 7 years: a whole season of life colored by this graha's agenda.
Mars rules Aries and Scorpio, is exalted in Capricorn (deepest at 28°), and is debilitated in Cancer (deepest at 28°) — exaltation is where a graha's nature works at its cleanest, debilitation where it has to work uphill. Mars counts the Sun, Moon, and Jupiter as natural friends; Venus and Saturn are neutral; Mercury is its natural enemy.
Good Mars is decisiveness with follow-through: physical vitality, protective instinct, the nerve to say the hard thing and take the hard step. It builds — engineers, athletes, surgeons, and everyone who makes reality obey a plan draw on it. Courage, at its best, is a form of kindness.
The blade unsupervised cuts the wrong things: impatience, temper, competitiveness that turns allies into rivals, accidents born of hurry. An afflicted Mars either fights everything or nothing. The discipline it wants is aim — heat pointed at a worthy target burns clean.
Engineering, the military and police, surgery, sport, construction and real estate, entrepreneurship's combative stretches. Mars pays best where boldness is a job requirement and worst where the work is mainly waiting. Land, classically, is its asset class.
Mars in relationship brings passion and protection but must learn the difference between winning and resolving. Its lesson: the partner is not the opponent, and gentleness is a strength setting, not a weakness.
BPHS styles Mangala the commander-in-chief of the grahas, fiery and kshatriya in temperament; Phaladeepika assigns it courage, siblings, and landed property. Its mahadasha runs seven years.
