सिद्धान्तशिरोमणि: गोलाध्याय (भास्कराचार्य - मरीचि भाष्य एवं पं. केदारदत्त जोशी सविस्तार व्याख्या)

पूर्णभगणशेषरूपयोजनेन" -> "स्यात्संपूर्व..." wait:
स्यात् + संपूर्ण = स्यात्संपूर्व... wait, "स्यात्संपूर्वण" NO!
"स्यात्संपूर्व" is s-a-m-p-u-r-v-a.
"स्यात्संपूर्व" has 'व'?
Let's look REALLY closely at that letter between 'पू' and 'भ':
Wait! Is it 'व' or 'ण'?
Look at line 3:
Look at 'ण' in "भगणशेषं": the 'ण' has a distinct loop.
Look at the letter after 'पू' in "स्यात्संपूर्व...":
Wait! It is 'ण' with a repha: 'र्ण'!
Wait, why would it be anything else? It's the exact same word repeated:
"...सम्पूर्णभगणशेषं स्यात् । संपूर्णभगणशेषरूपयोजनेन ज्ञाते सति..."
In Sanskrit discourse (vyākhyāna style):
"...स्यात् । संपूर्णभगणशेषरूपयोजनेन ज्ञाते सति..."
This repetition is standard anuvadak-vyākhyāna style (pratīka or summarizing the preceding conclusion to build the next sentence: "X स्यात् । X-रूपयोजनेन ज्ञाते सति...")!
So the word is definitely "संपूर्णभगणशेषरूपयोजनेन"!

Let's check line 4:
ज्ञाते सति चक्र
