Pranam Devotee ji

As far as i know Yadavas were Kshatriya and i have yet to read anything different. here is a link that may be of interest.

As for Parasar a Sudra that is news to me, do provide any avidence from Shastra where he may have been described as such.
If it is an opinion then i do not have to worry about that. It would be nice, were you to quote relevent Manu's Laws instead of me having to search for it.

As far as i know Gotra is passed on from Father to son. do let us know if you know any different. i also have read sometime ago that a Brahmin male could marry a lower varna but it is forbiden for brahmin girl to marry a lower varna.i will have to brush on this so dont take my word for it.

Jai Shree Krishna
