Subtract the figures of the Moon from those of the Sun; find what rasi the remainder represents. When Saturn and Jupiter pass through that rasi and navamsa or through the triangular positions corresponding thereto, the death of the mother may take place. Again, find the remainder resulting from the subtraction of Yamakantaka from the lord of the 6th bhava from the Moon. This remainder should indicate a certain rasi and a navamsa thereof. When Saturn passes through the rasi and the Sun through the navamsa in question, the mother may pass away.
