Brihat Jataka
चन्द्रलग्नान्तरगतैग्रहै: स्युरुपसूतिका: ॥ बहिरन्तश्च चक्रार्धे दृश्यादृश्येऽन्यथापरे ॥ ५-२२ ॥
The number of women attending etc on the mother of the child should be determined from the number of planets located in between the lagna and the Moon. Out of this number, those in the delivery room will be represented by the number of planets in the half of the zodiac from the lagna to the 7th house while those outside would be represented by the planets in the other half. Some teachers are of the contrary opinion that the half of the zodiac comprised of houses seven to the ascendant represents the number of women in the delivery room. (This is of course not the opinion recognised by Varaha Mihira).
