Brihat Parashara Hora Shastra
प्रकाशो गुणस्यापि वासः प्रकाशे धराधीशभ्रतुः सदा मानवृद्धिः । सुते भूसुते पुत्रकान्तावियोगो भवेद्राहुणा दारुणो वा निपातः ॥ ६७॥
Should Mangal be in Prakash, the native will shine with virtues and will be honoured by the king. Mangal in Prakash in Putr will cause loss of children and of wife. If Mangal is in Prakash in Putr and happens to be there with Rahu, a severe (positional) fall will descend on the native.
