यदा च तदेव प्रमेयं केनचित्सुबुद्धिना समरसिंहादिना अधीतं तदीयं ज्योतिःशास्त्रेण दृढतरसंस्काराद्व्यक्तसंज्ञापरिभाषेण संस्कृतशब्दैरुपनिबद्धश्चेत्पठ्यते तदा न कोपि दोष इति ज्ञेयम् ॥
That same subject was studied by some wise man, such as Samarasimha. His work was firmly grounded in jyotisha (astrology). It was set in Sanskrit words, with clear terms and rules. When such a work is read, know that there is no fault at all.
Simple meaning: No fault: reading Samarasimha's Sanskrit Tajika is allowed.
'न वदेद्यावनीं भाषामे'तद्वचनं तु यावनीयकाव्यालंकारादिविषयकमितिसिद्धांतः ॥
The ban explained: the rule against the foreign tongue is about foreign poetry, not this science.
ननु सूर्यसिद्धांतादिग्रंथास्तु श्रौतस्मार्तकर्मविषयकाः कथमस्य ताजिकशास्त्रस्य श्रौतस्मार्तकर्मविषयकत्वं ॥
A question: how does the Tajika help with sacred rites?
उच्यते ॥ "अष्टमे वर्षे ब्राह्मणमुपनयेत् षष्ठेऽन्नाद्यकामः"इति॥
Rite timing: the sacred thread at age eight, or at six for one who wants plenty of food.
