Hora Sara
स्वांशक्षेत्रगतो वा ग्रहयोगविवर्जितो निजोक्तगुणः। अन्यर्क्षग्रहयुक्तस्तद्ग्रहतद्वर्णमिश्रनिजवर्णः॥२३॥
A planet not conjoined with another, when posited in his own Kshetra or Amsa will reveal fully his natural qualities (such as colour, etc.); if, on the other hand, he be posited in another's Rasi (or Amsa) or conjoined with another planet, he would have his natural colour influenced by (mixed with) those of the Rasi or the planet as the case may be.
