Take Decisions out of Completion
Arjuna is now pleading Kṛṣṇa, 'Oh Lord, leave me! I will beg and eat becoming a Sannyāsi. I am confused as to which would be better, for them to slay me or for me to slay them, yadvā jayema yadivā no jayeyuḥ (2.6). How can we live after slaying our kinsmen and elders?, yān eva hatvā na jijīviṣāmas.'
Listen. Bhagavān is not against Arjuna's Sannyāsa. He does not want Arjuna to take Sannyāsa out of powerlessness. To become a Sannyāsi, Śrī Kṛṣṇa says, 'Go to Sannyāsa out of completion. Out of completion, take any decision!' He accepts Arjuna's decision to fight, because he took the decision out of powerfulness, completion!
Here begins the śāstras. Kṛṣṇa, fully aware of Arjuna's dilemma, moves forward in his mission to destroy Arjuna's identity, the root pattern. The Guru, Master is a surgeon who removes the cancer of ego, the root thought pattern. To give Arjuna credit, he stays through this surgery. Many weaker men would have run away from the operation theatre, this battlefield, with no desire to let go of their identities. Arjuna's greatness lies in his integrity, his decision to listen to his Master and be guided by Him.
We Never Cease To Exist (2.9-2.13)
Having lamented, Arjuna sits down saying, 'Govinda, I am not going to fight, na yotsya iti govindam (2.9).' Kṛṣṇa says to him gently and smilingly, 'While speaking learned words, you are mourning for what is not worthy of grief. Those who are wise lament neither for the living nor for the dead—gatāsūn agatāsūṁś ca nānuśocanti paṇḍitāḥ (2.11).'
A truly enlightened person will never worry for the living or the dead.' If you worry for somebody living or dead, you cannot be an intelligent person. What is death and life after all? There are thousands, rather millions, who have lived and gone.
