ग्रहराशिस्वरूपवर्षप्रवेशाद्यानयनाधिकारः
तथाच ब्रह्मसिद्धांते ॥संसाध्यं स्पष्टतरं बीजं नलिकादियंत्रेभ्यः॥तत्संस्कृतग्रहेभ्यः कर्तव्यौ निर्णयादेशावित्यलम्॥
So also in the Brahma Siddhanta: Find a truer bija (correction number) with the tube and other instruments. From the planets corrected by it, make both the decisions and the forecasts. That is enough on this.
Simple meaning: Brahma Siddhanta: measure the correction with instruments, then judge from the corrected planets.
अथ पञ्चाङ्गयंत्रादेव तात्कालिकीकरणेन स्पष्टग्रहानयनमुक्तं श्रीमन्नीलकण्ठदैवज्ञैः ।

अथ पञ्चांगीयनक्षत्रादेव चंद्रस्पष्टीकरणमुक्तं तैरेव ॥
Moon from the almanac star: the part of the star passed (from the end of the last star to now) and the star's full span.
खषड्घ्नं भयातं भभोगोद्धृतं तत्खतर्क ६० घ्नधिष्ण्येषु युक्तं २ द्विनिघ्नम् ॥
