Judge Every Planet First by Its Navamsa
नवांशस्थितिमादाय फलं ग्रहस्य निश्चिनु । राशिफलं तु पश्चात्तत् नवांशो बलवत्तरः ॥
First take up the navamsa position of every planet and decide its fruit from there; the rasi comes only afterwards, for between the two divisions the navamsa is the stronger witness. A planet seated poorly in the sign yet dignified in navamsa quietly keeps its promises, while the reverse placement betrays an outwardly bright promise.
The Birth-Star Lord Speaks First
जन्मनक्षत्रनाथो हि प्रथमं फलदः स्मृतः । तस्य संस्थानमाश्रित्य सर्वग्रहफलं भवेत् ॥
The lord of the birth asterism is remembered as the first giver of results; resting upon his condition, the fruits of all other planets are declared. Whatever star the Moon occupied at birth, that star's lord becomes the opening voice of the horoscope, and every later pronouncement is tuned to him.
Benefic or Malefic Is Decided by Lordship
स्वगुणैर्न तु ग्रहाणां शुभता जायते सदा । भावाधिपतिभावेन तयोः फलमुदीर्यते ॥
A planet's goodness is never born from his innate nature alone; it is through the houses he owns that his fruit is pronounced. Even gentle Jupiter turns harsh when he carries the lordship of sorrow-bearing houses, while a fierce planet turns protective once he guards the ascendant.
