जातकम् २
पुष्टं मध्यं लघु ज्ञेयं यदि चांशपतिर्बली ।राशीक्षणफलं रुद्ध्वा ददात्यंशफलं स्फुटम् ॥ २४२ ॥
In the full Narada Purana (Purva Bhaga) this is chapter 55, verse 242.
The results are to be known as full, middling or slight. Say the navamsha (one-ninth part of a sign) lord is strong. Then it holds back the result of the looks in the sign. It clearly gives the navamsha result.
Simple meaning: A strong ninth-part lord sets aside the sign results and gives its own.
शूरस्तब्धो विकलदृग्निघृणोऽर्के तनुस्थिते ।
The Sun in the 1st house gives bravery but weak sight. In Leo it can give night blindness.
नीचोधोस्वः कर्कगेऽर्के उद्बुदाक्षस्तनुस्थिते ।
The Sun rising in its low sign brings blindness, in Cancer bulging eyes. In the 2nd, wealth but mouth illness.
त्रिगे बुधो विक्रमी च विमुखः पीडितो भुवि ।
The Sun in the 3rd gives courage, the 4th trouble, the 5th few children, the 6th victory over enemies.
