Hora Sara
होरायामुदितांशप्रमाणमायुर्ददाति लग्नं च। पापग्रहे तु लग्ने चतुरंशस्त्यज्यतेऽन्यथा तु युतिः॥२५॥
The Lagna contributes for a man's life as many years as there are Navamsas that have risen. If there should be a malefic posited in the Lagna, the contribution for the Lagna will have to be reduced by onefourth. If, on the other hand, a benefic occupies it, the contribution should be enhanced by a fourth.
