अथ च ॥"म्लेच्छा हि यवनास्तेषु सम्यक्छास्त्रमिदं स्थितम् ॥ऋषिवत्तेऽपि पूज्यन्ते किम्पुनर्दैवविद्द्विजः" इति गर्गोक्तेश्च ॥
And further: 'The Yavanas are foreigners. Yet this science rests well among them. Even they are honoured like sages. How much more a twice-born daivajna (astrologer)?' So says Garga too.
Simple meaning: Garga: even foreigners who hold this science are honoured like sages, so a Brahmin astrologer even more.
यवनज्योतिर्ग्रन्थानामध्ययने द्विजानान्न दोषः ॥
Conclusion: Brahmins may study the foreign astrology books without fault.
अथ पङ्कोद्भवकमलादेरीश्वरपूजादौ त्यागस्स्यात्तथा भुजङ्गफणवर्त्तिमणिग्रहणेनादरस्स्यात् ॥
The objection fails: by that rule, the lotus from mud would be left out of worship, and a jewel from a snake's hood would not be valued.
उक्तञ्च गणेशदेवज्ञैः ॥
Ganesha Daivajna: though it came from the Turks, the Tajika is true, so good Brahmins may study it, like a lotus from mud.
