Ruchaka

Mars in the 1st, 4th, 7th or 10th house in Aries or Scorpio, its own signs, or in Capricorn, where it is exalted. No other house or sign produces Ruchaka, however strong Mars may look by other measures.

Start with the house. The 1st, 4th, 7th and 10th are the chart's angles, called kendras: the self, the home, partnership and work in the world. A planet in an angle is visible. It shapes the life rather than sitting in a corner of it.

Then check the sign. Aries and Scorpio are Mars's own signs, and Capricorn is its exaltation sign, the sign where a planet acts at its clearest. In Aries Mars moves from instinct, in Scorpio from strategy, in Capricorn from patience. The engine records which sign formed the yoga because the flavour differs.

Finally the engine asks whether the rest of the chart supports Mars. Ruchaka can form and still read as modest when Mars sits close to the Sun or shares its house with Saturn or the nodes. The page reports the combination; the reading weighs how much of it is available.

Angles are the houses of action. Mars is the planet of action. Put the two together and the chart has a planet of force in a position that can actually use it — not in a back room, but at the centre of how the person meets the world.

The sign adds the second half. Mars in Aries is quick, direct and competitive. In Scorpio it is private and relentless, willing to work where no one is watching. In Capricorn it is organised and patient, content to do unglamorous work for years to reach a position. The yoga is the same in name and quite different in texture, which is why the classical writers treated the five Mahapurusha yogas as signatures of character rather than fixed predictions.

• A capacity to decide and move before a situation becomes comfortable.
• Physical courage and stamina that show up at work as well as in sport.
• A reputation for finishing hard tasks, often under time pressure.
• Leadership earned by example rather than by title.
• A taste for contest that stays proportionate when the rest of the chart is settled.

• Mars in its own sign rather than only in exaltation, since familiarity gives judgement.
• An angle shared with no other planet, so Mars sets the tone of the house.
• Support from the Sun or Jupiter by aspect.
• No close contact with Saturn, Rahu or Ketu on the same degree.

Ruchaka is a permanent feature of the chart, and it is most visible when Mars runs its periods. The Mars mahadasha sets a long chapter of action; Mars antardashas inside other mahadashas open shorter windows. Mars transiting its own sign, or the angle it occupies, often marks a year of visible effort. The report builds these windows from the Vimshottari tree.

• Ruchaka does not mean conflict. It describes the capacity to act, which can build, defend or compete, and it serves a surgeon or a sculptor as readily as a soldier.
• The three signs do not give the same yoga in practice. Mars in Capricorn is usually the most organised expression, Mars in Aries the fastest, Mars in Scorpio the most private.
