Chapter 7 · Mind, Learning and Children: the 5th House
पञ्चमविवेकः
व्ययेशांशेशस्य त्र्यंशेशेन युते वा दृष्टे सुतेशे पुत्रनाशः ।
Take the lord of the 12th house. Take the lord of the navamsha (one-ninth part of a sign) it is in. Then take the lord of the drekkana (one-third part of a sign) of that navamsha lord. Say this planet joins or aspects the lord of the 5th. Then the sons will be lost.
क्रूरषष्ठ्यंशे पुत्रपे पापदृष्टयुते पुत्रार्तिः ।
Say the lord of the 5th is in a cruel shashtyamsha (one-sixtieth part of a sign). Say malefics join or aspect it. Then the person will suffer grief…
ज्ञाङ्गपौ लग्नेतरकेन्द्रगौ वंशविच्छेदः ।
Say Mercury and the lord of the 1st are in corner houses other than the 1st. These are the 4th, 7th and 10th. Then the family line will end.
पापग्रहा व्ययसुताष्टमगा वंशविच्छेदः ।
Say malefic planets are in the 12th, 5th and 8th houses. Then the family line will end.
