After repeatedly constructing one's own logic, admitting that one does not understand.

Arjuna, who said that a life of begging is better, still hasn't made up his mind. He admits that he doesn't know whether fighting or retreating is more desirable, and even whether they will win or the enemy will win.

Fighting is the duty of a Kshatriya, but he believes that fighting will bring about the sin of destroying his clan. Moreover, even if he wins, he may not want to live after killing his opponent. He finds no answer in either victory or defeat, and the more he analyzes his own reasoning, the clearer it becomes that he is at a dead end. For the first time, he realizes that he cannot determine the correct path on his own.

Japanese Translation from the Geeta Press Edition - Chapter 2, Section 6: "Whether to Fight or Retreat"

Even after stating his clear determination in this way, Arjuna was not completely convinced. Doubt arose within him regarding whether his attitude was correct or not. Therefore, he spoke further as follows:

Sanskrit original text

न चैतद्विद्मः कतरन्नो गरीयो
यद्वा जयेम यदि वा नो जयेयुः ।
यानेव हत्वा न जिजीविषामस्
तेऽवस्थिताः प्रमुखे धार्तराष्ट्राः ॥ ६ ॥

Romanization

na caitad vidmaḥ kataran no garīyo
yad vā jayema yadi vā no jayeyuḥ |
yān eva hatvā na jijīviṣāmas
te 'vasthitāḥ pramukhe dhārtarāṣṭrāḥ || 6 ||

We do not even know whether fighting or not fighting is more desirable for us. Also, we do not know whether we will win, or whether they will conquer us. The sons of Dritarashtra, who would not let us live if they could, are standing in the enemy ranks. (6)

"We do not know which is preferable," says Arjuna, indicating that he is in a state of being unable to decide whether or not he should fight.

On one hand, fighting is defined as the duty of a Kshatriya. However, on the other hand, it is declared that the destruction of family and clan as a result of such fighting is also evil and a sin.

Also, when Arjuna says, "I do not know whether we will win or whether they will conquer us," he is saying that even if it were deemed better to fight, he did not know whether the crown of victory would come to their side or be taken by the enemy.

Furthermore, when Arjuna says, "The sons of Dhritarashtra, who would not even want us to live if they could kill us, are standing before us," he is expressing that, even if they were to win the battle, it would still be undesirable to engage in such a conflict.

Because Duryodhana and the other members of his family, who were Arjuna's close relatives, were standing right in front of him, ready to die in that battle. If he killed them, Arjuna would not even want to live. Even if he achieved victory, it would be a victory obtained by causing the deaths of his own relatives.

Therefore, Arjuna was confused and troubled, and he could not decide for himself which path he should take.
