Hora Sara
क्षेत्रोच्चमित्रभागे ग्रहैः समस्तैस्तदांशजनितश्च। अर्केन्दुलग्नरहितैर्ग्रहैस्तदांशोद्भवो दशामार्गः॥२०॥
When all the planets are posited in their own houses, exaltation signs or friend's houses or Navamsas, then the Amsayurdaya system should be adopted; so also will be the case when planets are not associated with the Sun, the Moon or the Lagna.
