ग्रहचारः केतवश्च
सौम्यायने क्षत्रविप्रानितरांहन्ति दक्षिणे ।द्विजातींश्चक्रमाद्धंति राहुदृष्टोरगादितः ॥ ८९ ॥
In the full Narada Purana (Purva Bhaga) this is chapter 56, verse 89.
In the Sun's northern course, an eclipse may put warriors and priests at risk. In the southern course it may put the others at risk. Seen first in the north and the other directions, Rahu may trouble the classes in order.
Simple meaning: An eclipse in the Sun's northern course may harm warriors and priests; in the southern, others.
तथैव ग्रामभेदाः स्युर्मोक्षभेदास्तथा दश ।
Eclipses have ten kinds of covering and ten of release. Even gods cannot tell them all.
आनीय खेटान्गणितांस्तेषां वारं विचिंतयेत् ।
Work out the planets and watch their movement. They show the good and bad of the time.
तस्मादन्वेषणीयं तत्कालज्ञानाय धीमता ।
A wise person watches the rising and setting of comets to know the time and its results.
