It seems strange that the most intense, thought - provoking, philosophy laden discussions take place in the most bizarre and tense circumstances.
The Yudhi- Yaksha samavada took place beside the dead bodies of his brothers, on the shore of a poisonous lake.
The Bhagavata Gita took place...well everyone knows where
The third most significant discussion place when Bhishma with arrows pierced all through his body, was counting the number days till Uttarayan.
With sixty five days more to go, Krishna approaches the Grandsire and asks him to impart all the knowledge he had acquired through scriptures, experience and from learned men to Yudhishthira, the would be king of Hastinapura.
Bhishma asks with a smile - Why doesn't Krishna do the same? Why make this old man, struggling with pain and fatigue impart wisdom to Yudhishthira? After all Krishna was equally capable, if not more capable.
Krishna told Bhishma that though he could give these teachings to Yudhishthira, he wanted Bhishma's name and righteousness to be remembered forever. Your utterances will be on a par with the Vedas and will bring undying glory to you."
Then Krishna gave Bhishma a special boon: I will grant you a boon. This pain and this weakness will not be there till you die. Your memory will be unclouded. Your perception will be as keen as the blade of a sword. You will be able to unravel the most intricate knots of the mysteries of the universe. You will know all that there is to know.' Whereupon Krishna removed all of Bhishma's pain and distress, so that his faithful devotee might perform his final duty to him.
Thus begins one of the most comprehensive lectures on State Governance. Covering the latter half of the Shanti Parva and the whole of the Anushasana Parva, Bhishma discourses on matters relating to Rajyaneeti, Arthaneeti, Danda neeti and Praja neeti.
I am of the opinion that a discussion on the merits of Bhishma's discourse is irrelevant today, since everything has changed from the days of Dwapara Yuga till today.
What Bhishma preached may have been relevant in those days; it's efficacy cannot be measured today.
