I have read various stories and heard various stories about Gajasur, but none where it is Gajasur's head for replacing Vinayak's. There were no comments on this story - so I figured that this story or some form of it must exist somewhere.
I understand that Gajasur voluntarily donating his head is a vehicle used to keep in step with the animal rights views of the present time. No problem with that.
The thing is from what I understood, Gajasur has a boon that he will live with Mahadev and attain great wisdom (did I understand the dialogues correctly - sometimes I get lost). If that is the case, then when Mahadev revives Vinayak :
1. Is it the body of Vinayak and the head + soul of Gajasur
Because if Gajasur has to stay with Mahadev then it should be his soul;
but then what about Parvati's son Vinayak
2. Is it the body & soul of Vinayak and the head of Gajasur
- in this case what of Gajasur's boon
Please don't laugh at me. I know I sometimes ask strange questions
