Which character's sacrifice was completely overlooked in the Ramayana and Mahabharata? Did Bheeshma do a great sacrifice? Yes but his sacrifice was not alone the greatest. There was someone else too. In today’s world, it isn’t hard to find a person who sacrifices his throne and promises to stay single. We have someone close Abdul Kalam. He remained single for his work and would have left president post too if there was a requirement. Someone can say Bheeshma slept on arrow bed for days before he died. We have Heroic Sambhaji who suffered unimaginable pain but did not convert. All I am saying is even today we can find people who did what Bheeshma did. Now just imagine, You are a princess of a kingdom, one day you have to marry a blind man and you with your own will decide to be blind rest of your life. I can understand if she would have damaged her eyes. But tying a cloth? She has to struggle all her life with, Temptation to see husband, doomed physical pleasure, eager to see newly born hundred children, not being able to select spouse for her children, missing the visuals of their marraige, above all not being able to ask help to the closest man, her husband because he too is blind. Poor lady never expected anything in return. Just pure sacrifice for the love for a blind man. Above all Gandhari was not affected by even 1% due to the crooked brother Shakuni. For me Gandhari’s sacrifice is also Bheeshm sacrifice. However, she is overshadowed.
