As far I went down the ancient sanskrit traditions, I also think this numbering system has deep ties to numerology, astrology and derived spiritual disciplines like raga (classical carnatic music, hindustani) and classical dances like Kathak, all of which are studied through numbers, patterns and thus math. Though I'm sure I'm missing something.
