Brihat Parashara Hora Shastra
कर्माधिपो बलोनश्चेत् कर्मवैकल्यमादिशेत् । सैहिः केन्द्रत्रिकोणस्थो ज्योतिष्टोमादियागकृत् ॥ ३॥
If Karm‟s Lord is devoid of strength, the native will face obstructions in his work. If Rahu is in an angle, or in a trine, he will perform religious sacrifices, like Jyotishtoma.
