Hora Sara
गृहैक्यस्य दशाभावे भेदमार्गं प्रकल्पयेत्। तदोच्चनीचमार्गेण दशां कुर्याद्विचक्षणः॥६३॥
In the case of any difficulty in ascertaining the Dasaperiods of planets owing to their being conjoined with other planets, a different method should be resorted to. A clever astrologer should calculate the Dasas of the planets through their exaltation and depression positions.
