The episode begins with Shastriji telling the Panchayat in the Aachar Sanyataa's 15th chapter, it is specified that for if a Rajpurohit's wife has left him, before getting married again he has to apologise to all five elements before which he got married the first time- this is called the kshama vrat (forgiveness fast).
May be chapter 16 has details of what a RP should do if he makes a mistake by accident ..
Or may be Radhika should read the Rajpuroit book that maharaja gave her ..
I dont know what the answer is .. but, cant take this anymore .. I feel sorry and sad for Dev!
But, I am not going to quit but, wait and watch ..
