“assertion of the American indologist Whitney maintained to this date among Abrahamistic white indologists and their imitators: “The Hindus borrowed their nakShatra system from Mesopotamia and would probably have retained it in that form [i.e. with kR^ittikA at the vernal equinox of 2300 BCE] until the present day but for the revolution wrought in their science by Greek teaching.” Clearly even within the vaidika period (including vedA~Nga jyotiSha) the Hindus had made multiple changes for precession not just at the time of varAhamihira after interactions with yavana-s.” [MT]
