Why do you think the second category of texts was not written down?
Answers
The texts belonging to the first category are easier to date, as several manuscripts have been found indicating that they were composed between the late circulation orally and mid-eighteenth centuries. Those belonging to the second category cicrulated orally and cannot be precisely dated. They were particularly popular in eastern Bengal, where the influence of brahmanas was relatively weak.
