The question raised by Harsha Dehejia is complicated for several reasons.
First, there are different concepts of zero, leading to different mathematical
and philosophical problems. In particular, if zero is a number that may be
subject to subtraction, then it is necessary to introduce negative numbers
(minus five as zero minus five for instance). Now this step was first taken by
Brahmagupta in his Braahmasphu.tasiddhaanta (chap. 18), which happens to be
roughly the time of the first attestations of the lingodbhava theme, in which
we find a two-sided infinite (see my paper in the volume on "Mythes d'origine",
as well as my communication at the French Académie des Inscriptions et
Belles-Lettres in 2018 -- full references are on my web page). Thus, there are
several philosophical ideas involved here, not just the idea of vacuity, but
also those of: infinity, absence of origin, infinite universe.
In addition, there are several words for the same mathematical notion of zero.
Thus, the word kha and synonyms, referring to an empty place, are equally
important.
About Hellenistic mathematics, it is true that zero is not considered, but even
the monad ("one") is not a number: the smallest number is supposed to be two.
There have also been at a realtively late date, what may be called negative
reactions to negative numbers.
I hope this helps,
