एवं हि तत्कारकतो विचिन्त्यं पितुश्च मातुश्च सहोदरस्य । तन्मातुलस्यापि सुतस्य पत्यु- र्भृत्यस्य सूर्यादिखगस्थितर्क्षात् ॥ २१॥
In the same way should the effects of the father, the mother, the brother, the maternal uncle, the son, the husband and the servant be determined by treating the signs occupied by their respective Karakas, viz., the Sun, the Moon, and other planets, in the nativity as the Lagna (Ascendant).
