जातकम् २
अशून्येषु च केंद्रेषु कारकाख्यगृहेषु च ।गुरुजन्मेशलग्नेशाः केंद्रस्था मध्यसौख्यदाः ॥ २७४ ॥
In the full Narada Purana (Purva Bhaga) this is chapter 55, verse 274.
So is birth when no kendra (corner house) is empty. So is birth with planets called karaka (the planet that stands for a thing). Jupiter, the birth-sign lord and the lagna (rising sign) lord, in a kendra, give middling comfort. (Our text is unclear here: 'madhya' may mean middling or in the middle period.)
Simple meaning: Full corner houses and karaka planets help. Jupiter and the Moon-sign and lagna lords there give moderate comfort.
अन्योन्यकारकास्ते स्युः कर्मगस्तु विशेषतः ।
Strong planets in corner houses help each other. Birth in a vargottama sign is good.
पृष्ठोभवकोदपर्क्षस्थितास्त्वंत्यांतरादिषु ।
Sun and Mars act early in a dasha, Venus and Jupiter in the middle.
चंद्रार्की फलदावंत्ये सदा ज्ञः फलदायकः ।
The Moon and Saturn act late in a dasha. Mercury acts all the time.
