Jataka Tattva · by Mahadeva
Chapter 5 · Brothers and Livelihood: the 3rd House
सहजविवेकः
सोत्थपे वा कारके त्रिके पापेक्षितयुते स्वोच्चे वा भ्रातृहानिः
Take the lord of the 3rd, or the karaka (the planet that stands for a thing) of brothers. Say it is in the trika (group of three houses). Bad planets aspect or join it. Then the person loses brothers, even if it is in its own uchcha (high point) sign.
सोत्थगैः पापैर्बाल्ये भ्रातृहानिः ।
Say bad planets are in the 3rd house. Then the person loses brothers in childhood.
सोत्थपे तत्कारके वा पापैर्युते भ्रातृहानिः ।
Say bad planets join the lord of the 3rd. Or they join the karaka (the planet that stands for a thing) of brothers. Then the person loses brothers.
सोत्थे मन्दे भौमदृष्टेऽनुजहीनः ।
Say Saturn is in the 3rd house and Mars aspects it. Then the person has no younger brother.
