ग्रहराशिस्वरूपवर्षप्रवेशाद्यानयनाधिकारः
अत्र शास्त्रे तु वर्षफलप्रश्नादिजिज्ञासुरधिकारी स च ब्राह्मण एव ॥
Who is fit to study this science? One who wants to know the year's results, questions and the like. And he must be a Brahmin.
Simple meaning: Who may study it: one who wants to know the year's results, a Brahmin.
उक्तंच वसिष्ठेन ।
Vasishtha: astrology is a holy science for Brahmins; it brings wealth, right living, freedom and fame.
ननु यवनाचार्य्यप्रणीतेक्कवालादिपारसीशब्दात्मकस्य ताजिकशास्त्रस्याध्यापनमेव तावदनभिहितम् ॥ अध्ययनं तु दूरादपास्तमेव ॥
An objection: the Tajika uses Persian words, so teaching and studying it seem not allowed.
उक्तं च स्मृतौ ॥
The Smriti rule: never speak the foreign tongue, even when close to the end.
