Brihat Parashara Hora Shastra
लाभेशे लाभभावस्थे पापदृष्टिविवर्जिते । कारके शुभसंयुक्ते लाभस्तस्य नृपालयात् ॥ १२॥
One will gain through royal association, if Labh Bhava is occupied by its own Lord and is devoid of a Drishti from a malefic. The Atma Karak should at the same time be yuti with a benefic.
