Ghori, prithvi and sanyogita.

My earlier posts was on swayamvar and now I have found out some info on how prithvi died. Acc to this what chand wrote in prithvi raj raso is false. Jaichand had joined forces with ghori coz he thought that prithvi had forcefully taken his daughter from her swayamvar. Prithvi tried to talk to his father in law about the consequences but to no avail as jaichand was mad with rage. Also many kings had withdrawn their support to prithvi as they were scared of ghori though prithvi had defeated ghori many times. So before going to battle(the last battle) prithvi knew that he may not win this time. And had said so to sanyogita, she had replied that if something happened to prithvi she will also kill herself as she could not live without him. so when the battle started the fortune at first favoured prithvi but then it favoured ghori and after an intense fight prithvi was killed. And sanyogita heard the news, she quietly dressed in her bridal clothes and joined her husband in his funeral pyre(this means she did sati). Here also I say the same thing – its belive what you like and I am sure sagar's will stick with chand bardai's book prithvi raj raso.

PRC killed ghori in afghan...so how can there be a funeral for him with sanyo doing sati? Sanyo commited juhar.
