well, i haven't read p.r. ras., but after a long disscussion with my parents, that scene with the guru is a dream of prithvi, it did not happen in real. an' in the 2nd december episode, that part of suciding one, was just to show that, prithvi, being from a high family, used to consider people below him as his equal or as friends.
that jwala stuff, jwala had brought a bow with her. 'coz she needed some khazana to help her family. so, in that dream, what she told prithvi of helping prithvi, an' prithvi understanding what she wanted showed that prithvi was intelligent
by da way, before the serial starts, there's some kind of written note about, history of rajasthan by james todd, p.r. raso by chandra bardai.......etc etc......on the last line they some characters are fictional.
i hope that helps. this is my opinion
