Ans. Why only Arjun got unnerved in MAHABHARAT?
Standing on the brink of that historical war, it was not his army but Arjun who was unnerved. The army was fully in readiness to fight. Doesn’t it imply, then, that by preaching to Arjun, Krishn had only conferred on his beloved friend and disciple the ability to be worthy of his army? In fact, the whole of the means for spiritual accomplishment cannot be put down in black and white. Even after one has gone through the Geeta several times, there is yet the necessity of actually traversing the path of God-realization that the Lord has charted.Let us discuss why only Arjun was unnerved?

Krishna Leela...
Dear Ones, If you read the Mahabharata carefully, you will notice that during the period where the Pandavas were to live incognito, Arjuna fought the Bheeshma Pitamaha, Acharya Drona, Kauravas, Karna etc & single handedly vanquished all of them. Arjuna's state of mind prior to the great war was part of a Leela (Act) of Shri Krishna, where by He could directyl give the Divine Knowledge of the Bhagwad Gita to His friend, Devotee & Disciple, the Warrior Prince Arjuna. This knowledge is a synopsis of the knowledge of all the Vedas, Upanishads & all the Holy texts put together... We thank the Lord for brining Arjuna to the frame of mind due to which Arjuna got the Divine Knowledge of the Gita. This knowledge has been passed onto us from generation to generation & like an unending river will continue enriching generations to come....Hare Krishna to all....
