Jataka Tattva · by Mahadeva
Chapter 3 · Body, Nature, Health: the 1st House
प्रकीर्णतत्त्वम् : अङ्गविचारः (प्रथमविवेकः)
यो भावः स्वस्वामिशुभैर्युक्तो दृष्टो वा तस्य वृद्धिः पापैर्हानिर्मिश्रैर्मिश्रम् ।
Say a house is joined or aspected by its own lord and by good planets. Then that house grows. If bad planets join or aspect it, the house suffers loss. If mixed planets do, the result is mixed.
नीचारिस्थो ग्रहो भावनाशकः ।
Say a planet is in its nicha (low point) or in an enemy's sign. That planet spoils the house it holds.
स्वसुहृत्तुङ्गस्थो भाववृद्धिकरः ।
Say a planet is in its own sign, a friend's sign or its uchcha (high point). That planet makes the house it holds grow.
यद्भावात् त्रिके पापास्तद्भावनाशः ।
Say bad planets are in the 6th, 8th or 12th house counted from a house. Then that house is lost.
