Brihat Parashara Hora Shastra
उक्तेष्वेषु बली योगो निर्बलस्य प्रबाधकः । न रन्ध्रेशत्वदोषोऽत्र सूर्याचन्द्रमसोर्भवेत् ॥ ७॥
The Grah, owning a predominant Bhava, will stall the effects, due to another, owning a less significant Bhava and will give his own results. Randhr‟s lordship of Sūrya and Candr is not evil.
english translation
