What does Krishna say would be shameful for Arjuna?

In the Bhagavad Gita, Krishna emphasizes the importance of duty, especially in the context of Arjuna's role as a warrior. He tells Arjuna that not going to war, despite being called to fulfill his kshatriya (warrior) duty, would be shameful. Arjuna is facing a moral dilemma about fighting against his own relatives and teachers on the battlefield of Kurukshetra. Krishna argues that choosing inaction or retreating out of fear would not only be a dereliction of Arjuna's responsibilities but also a sign of weakness that contradicts the values of a warrior.

Krishna presents this perspective to motivate Arjuna to adhere to his dharma (duty) and recognize the necessity of engaging in the battle, which is deemed righteous in this context. The shame mentioned is tied to the loss of honor and duty in the face of the greater good and the spiritual teachings Krishna imparts regarding selflessness and action. This reinforces the central theme of the Gita, which emphasizes active engagement in one's responsibilities rather than avoidance based on fear or personal conflict.
