Secret of 'Bandh Kamraa'??

I ws thinking a lot of this...bt i'm really confused..n not able to reach an answer...

I'm not sure if anyone here has seen Saath Phere but there was a track which was quite similar to the one happening in this TMHPKNK. In that show, there was also a bandh kamra with a raaz that no one was willing to tell to the female lead... And finally when the truth of that room saw light, it had to do with 'another woman'. Actually the other woman was the first wife of the male protagonist and her belongings were still in that room, sorta like the guy's bad past. So I'm not absolutely positive if the same thing will occur in Pehle Ka Naata as this so called 'shraap' has been present since 70 years but I have this gut feeling that it has something to with a women, that's for sure. :P

And I really don't know how can it be related to Tashi... maybe re-birth or something of the sort?
