Bhagavad Gita

ಯದಿ ಮಾಮಪ್ರತೀಕಾರಮಶಸ್ತ್ರಮ್ ಶಸ್ತ್ರಪಾಣಯಃ ।
ಧಾರ್ತರಾಷ್ಟ್ರಾ ರಣೇ ಹನ್ಯುಸ್ತನ್ಮೇ ಕ್ಷೇಮತರಂ ಭವೇತ್ ॥೪೬॥
yadi māmapratīkāramaśastram śastrapāṇayaḥ |
dhārtarāṣṭrā raṇe hanyustanme kṣemataraṃ bhavet ||46||

Sloka 1:46
Gist of the sloka:
If Emperor Dhitrarastra was to appear in front of me to kill me, who has held a weapon in his hands but would not want to fight, I would consider such a death my greatest blessings.
I would not react even when they come to attack me. If they kill me even when I am holding a weapon, I would not use it. I would rather consider such a death my greatest blessings. How can I see such destruction and continue to live? Whatever happens I no longer wish for the battle. Arjuna completely collapses overwhelmed with confusion and emotional stress.
It was the same Arjuna who commanded Lord Krishna to stop the chariot in between the armies. He had enormous confidence at that time. Lord Krishna noticing the ego which had crept into Arjuna, parked the chariot so that deep unconscious feeling that Arjuna had within himself [without he being aware either] would first come out.
Moment Arjuna saw his elders his deepest emotional feelings towards his relations came out and affected his confidence.
One of the critical aspects of any psychotherapy is to first bring out the hidden thoughts, emotions of the person before actually starting the therapy. Lord Krishna being the first such therapy doctor demonstrates to the world as to how it has to be done.
