Phaladeepika
रूपं मानुषभेऽलिभेऽङ्घ्रेरपरेष्वर्द्धं बलं स्यात्तनोः तुल्यं स्वामिबलेन चोपचयगे नाथेऽतिवीर्योत्कटम् । स्वामीड्यज्ञयुतेक्षिते कवियुते चान्यैरयुक्तेक्षिते शर्वर्यांन्निशि राशयोऽहनि परे वीर्यान्विताः कीर्तीताः ॥ ६॥
If the first Bhava be a biped sign, ono Rupa has to be allotted to it; if it be Vrischika, the bala is 1/4; if it be any other sign, the strength is 1/2. The strength of the Lagna is equal to that of its lord and is very powerful when the lord occupies an Upachaya (3 rd, 6 th, 10 th or 11 th) house. The same is also the case when it is occupied or aspected by its lord, Jupiter or Mercury, when it is associated with Venus and is at the same time without the conjunction or aspect of any other planet. The day-signs possess strength in daybirths, while night-signs are declared powerful in night-births.
