Brihat Parashara Hora Shastra
उच्चचेष्टाकरान् व्येकान् दिग्भिर्हत्वा तु योजयेत् । तदर्धमिष्टसंज्ञं स्यात् कष्टं तत्षष्टितश्च्युतम् ॥ ६॥
Isht and Kasht Tendencies. Reduce 1 from each of Chesht Rasmi and Uchch Rasmi. Then multiply the products by 10 and add together. Half of the sum will represent the Isht Phala (benefic tendency) of the Grah. Reduce Isht Phala from 60 to obtain the Grah‟s Kasht Phala (malefic tendency).
