Jataka Tattva · by Mahadeva
Chapter 6 · Mother and Home: the 4th House
चतुर्थविवेकः
वृश्चिकांशे मातुर्दुग्धशोषः ।
Take the navamsha (one-ninth part of a sign) of the atmakaraka (the planet that stands for the self). Say it is Scorpio. Then the mother's milk dries up for the child.
खे कुजेऽष्टमे जीवे बलाढ्ये मातृसुखं न ।
Say Mars is in the 10th house. Jupiter is strong and in the 8th house. Then there is no happiness from the mother.
षष्ठाष्टमे चन्द्रेऽस्ते भौमे सपापे मातृसुखं न ।
Say the Moon is in the 6th or 8th house. Mars is in the 7th house with bad planets. Then there is no happiness from the mother.
शुक्रे वा चन्द्रे पापान्तरे पापयुतदृष्टे वा मातृसुखं न ।
Say Venus or the Moon is between bad planets. Or bad planets join or aspect it. Then there is no happiness from the mother.
