Arjuna said: By your grace, O Krishna, my delusion is gone, memory (of my true identity) is regained; I stand with doubts dispelled. I shall do as you say.
How quick and complete is Arjuna’s response! He first acknowledges Krishna’s grace on him, in having delivered excellently such a relevant and explicit message. He was deluded, but the delusion is gone for good!
Arjuna should not have reacted and behaved the way he did. He had totally forgotten that he was a kshatriya and it was in pursuit of his dharma that he had come to the battlefield, to contend those who opposed him and the values he and his army held. All other considerations should have been subservient to this. But everything went topsy-turvy and the whole memory had slipped. Now he has gained it back and is stable.
He no more has any doubt. In the battlefield, he should think only of vanquishing the opponents. He would do this valiantly.
