Look at the second digit of 1918: it looks identical to the digit in line 18!
And 1918 is obviously ১৯১৮ / १९१८ (April 2, 1918)!
So that digit IS ९ (nine)!
Wait, why did I think it was ६? Because in this font, ९ is shaped like a reverse curve or modern 9: a curve, loop at top, or curved like 9!
Wait, in line 30, it is "ई. स. १९१८" (1918)!
Wait, what about line 15: "ई. स. ६६३"?
Wait! In line 15, is it "६६३" or "६६३"? The first two digits are ६, ६! They are shaped like ६.
In line 30: "१९१८" -> first digit is १, second is ९, third is १, fourth is ८!
So that second digit is ९!
And in line 18: "८७ और ९१ के" -> the digit in ९१ is identical to the ९ in १९१८!
So it is definitely ९१ (91)!
Wait, what about line 19: "ई. स. ६६३ ६ के"?
Wait, is line 15 "ई. स. ६६३" or "ई. स. ६६३"?
Wait, Indra-bhattaraka died in
