तथाच"कृते पैतामहं शास्त्रं त्रेतायां बादरायणम् ॥गार्गीयं द्वापरे प्रोक्तं सुसत्यं ताजिकं कलावि"ति जीर्णताजिकोक्तेः ॥
So too: 'In the Krita age, the science of Pitamaha. In the Treta, that of Badarayana. In the Dvapara, that of Garga is told. In the Kali age, the Tajika is very true.' So says the Jirna Tajika.
Simple meaning: The Tajika for this age: each age had its science; in the Kali age the Tajika is true.
अथ च ॥
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.
