Chapter 12 · The 10th House, Work and Standing
दशमविवेकः
चतुर्षु स्वगेषु शत्रुभगेषु वा नीचांशगेषु व्यर्था राजयोगाः ।
Say four planets are in their own signs. Or they are in enemy signs, or in debilitation navamshas (one-ninth parts of a sign). Then the royal combinations come to nothing.
ग्रहमात्रादृष्टश्चन्द्रो वा लग्नं व्यर्था राजयोगाः ।
Say the Moon or the 1st house is looked at by no planet at all. Then the royal combinations come to nothing.
सिंहांशेऽर्के पापयुते क्षीणेन्दौ सौम्यादृष्टे व्यर्था राजयोगाः ।
Say the Sun is in a Leo navamsha (one-ninth part of a sign) and joined by a bad planet. Say the Moon is waning and no good planet looks at it. Then…
परमनीचांशे जीवे वा शुक्रे व्यर्था राजयोगाः ।
Say Jupiter or Venus is at its deepest debilitation point. Then the royal combinations come to nothing.
