When a planet is placed in a kendra (1st, 4th, 7th or 10th) from the lagna or the Chandra lagna, and is in its exaltation or own sign, it is designated a Mahapurusha yoga.
Verse 2 — Ruchaka and Bhadra Yogas
भौमे मेषवृश्चिके च मकरे वा केन्द्रगे। रुचको योग उतपन्नः शुभ्रे भद्रः प्रकीर्तितः॥
Mars in Aries or Scorpio, or exalted in Capricorn, when placed in a kendra, gives rise to Ruchaka yoga; Mercury similarly dignified in a kendra is celebrated as Bhadra yoga.
Jupiter gives Hamsa, Venus gives Malavya, and Saturn gives Shasha yoga; these planets in kendra in their own or exaltation signs yield the auspicious fruits of a Mahapurusha.
