Importance of Vishnu Sahasranamam

The Vishnu Sahasranamam is found in the Mahabharatha. Literally translated this means thousand names of Vishnu. This is found in the Anushasanika Parvam (chapter relating to orders or rules to the kings) of Mahabharatha. Bheeshma Pitamaha was defeated and grievously wounded by Arjuna. But since he could choose the time of his death as per the boons received by him, he chose to die in Uttarayana and was waiting for the auspicious time. Meanwhile the war was over leading to death of all those male members in his family except the Pancha Pandavas and the unborn child of Abhimanyu. Yudishtra the eldest of the Pandavas became the King of Hasthinapura and went to Bheeshma the great for the advice 
In Bhishma's expert judgment, chanting Vasudeva's name with devotion and sincerity will ensure relief from sorrows and bondage. This in a nutshell is the phala sruti or the benefit of chanting Sri Vishnu Sahasranamam.
