Īśopanişad on Pūrņa
The Śāntimantra of Īśopanişad talks of the Infinite, Pūrņa: When pūrņa is taken out of pūrņa, what remains is also pūrņa.
पूर्णमदः पूर्णमिदं पूर्णात्पूर्णमुदच्यते ।
पूर्णस्य पूर्णमादाय पूर्णमेवावशिष्यते ।।
Bhāskarācārya on Khahara
Bhàskaràcàrya II (c.1150), while discussing the mathematics of zero in Bījagaņita, explains that the infinity (ananta-rāśi) which results when some number is divided by zero is called khahara. He also mentions the characteristic property of infinity that it is unaltered even if many are added to or taken away from it, in terms similar to the invocatory verse of Īśopanişad.
खहरो भवेत् खेनभक्तश्च राशिः ।।
द्विघ्नं त्रिहृत् खं खहृतं त्रयं च ।
शून्यस्य वर्गं वद मे पदं च ।।...
अयमनन्तो ३/० राशिः खहरः इत्युच्यते ।
अस्मिन्विकारः खहरे न राशावपि प्रविष्टेष्वपि निःसृतेषु ।
बहुष्वपिस्याल्लयसृष्टिकालेऽनन्तेऽच्युते भूतगणेषु यद्वत् ।।
[बीजगणितम् १४-१६ वासना]
A quantity divided by zero becomes khahara.
Tell me … three divided by zero … This infinite (ananta) quantity 3/0 is called khahara.
In this quantity khahara there is no alteration even if many are added or taken out, just as there is no alteration in the Infinite (ananta) Infallible (acyuta) [Brahman] even though many groups of beings enter in or emanate from [It] at times of dissolution and creation.
There is no parallel discussion in modern mathematics till recent centguries
