Mangal (Mars) stands in its own or exalted sign in the 1st, 4th, 7th or 10th house: Ruchaka, one of the five Mahapurusha ('great person') yogas. It makes you sturdy and energetic, with a strong brow and a fighter's nerve. You beat rivals, are drawn to discipline and mantra, and have a charitable nature rooted in the customs of your birthplace. It suits work that asks for command — the army and police, surgery, engineering, sport, land and building — and comes alive in Mangal's dasha.
