1st House Ruler in House VII - Marriage & Relationship
Parashara Hora Shastra
If Lagn's Lord is a malefic and is placed in Yuvati Bhava, the natives wife will not live (long). If the Grah in question is a benefic, one will wander aimlessly, face penury and be dejected. He will alternatively become a king (if the said Grah is strong).
