This is exactly what i meant in my post about Sam's death giving rights to Sai she has been denied so far.
First off, there's no havan in funeral rituals. I don't know what ghum is trying to do.
Secondly as the elder and married couple of CN... Only Ninad Ashwini or SaiRat can do it.
If they are unavailable then Sonkar and Mohrishma.
But even though BK considers Pakhi as badi Bahu... She technically cannot participate and be in any ritual concerning Chavans as she is Salunkhe and now a widow.
For all social and cultural understanding... Sai always had this right but was denied to her by BK for her extra love of Pakhi. Remember Basant panchami and Mahashivratri where Pakhi cannot sit in the Pooja even though BK wants her too.
With his death, Pakhi has lost that chance forever. Whatever BK might say.. till Sai is married to V... In their generation, Sai has this right now that no one can deny her.
Unfortunately it took Sam's death for her to get that right 😭
