Phaladeepika
चन्द्रात्सुखफलैः पिण्डं हत्वा सारावशेषितम् । शनौ याते मातृहानिः त्रिकोणर्क्षगतेऽपि वा ॥ ७॥
The figure indicating the sodhyapinda in the Moon's Ashtakavarga should be multiplied by the number representing the benefic dots in the 4 th house counted from that occupied by the Moon. The product should be then divided by 27. When Saturn transits the asterism (counted from Aswini) indicated by the remainder or its triangular star, the demise of the mother may be expected.
