Brihat Parashara Hora Shastra
स्वगेहे स्वांशके स्वोच्चे सुखस्थानाधिपो यदि। भूमियानगृहादीनां सुखं वाद्यभवं तथा॥ ३॥
The Yuti of Putr‟s Lord with Lagn‟s Lord in a good Bhava will ensure early obtainment of children apart from happiness through them. If they join in an evil Bhava, they will prove a defect in this respect.
english translation
