i have heard from one version that Sati prayed to Mahadev during her Swayamvar and garlanded Shiv when he appeared by Chanting Om Namah Shivah...and yes Daksh was completely against it...that is why he organized the swayamvar
another one says she did heavy penance for him-but i guess that is because many texts mess up the Uma/Gauri/Parvati/Sati thing and confuse Sati to be Parvati!
but yes form what i have read -the Shiv Purana states the marriage took place without any hassle at all,and Daksh though a little reluctant initially did get the marriage done!
regarding the PRC copy thingy..yeah...that was bittt too filmy...š
but the reason why they choose to show the Swayamvar was to justify in the long run Dakshas hatred towards Shiva and his own daughetr..my pov entirely!
but in a way,im happy beacause atleast issi bahane people are watching something that is inspired from out sacred texts and will go ahead and learn more...ive seen people searching google to find the real story and get enlightened!...so thats one good thing of the slight over dramatization!
