Krishna uses the analogy of life’s stages – childhood, youth, and old age – to illustrate the soul’s transition from one body to another. He encourages Arjuna to perceive death as a natural transformation rather than an end. This teaching is meant to reduce Arjuna’s attachment to the physical body and ease his fear of death’s finality.

Krishna advises Arjuna to endure pleasure and pain as mere interactions between senses and objects. He points out that these sensations are temporary, encouraging Arjuna to rise above them and maintain equanimity. This lesson serves as an introduction to the concept of detachment, which will be elaborated upon in the subsequent teachings.

Krishna declares that one who is not disturbed by happiness or distress and remains calm in both is eligible for liberation. This shloka highlights the importance of equanimity, suggesting that spiritual growth is achieved through steadfastness and inner strength, rather than succumbing to the fleeting nature of worldly experiences.

Krishna reassures Arjuna that the soul, which pervades the entire body, is indestructible. By asserting the soul’s invincibility, Krishna aims to alleviate Arjuna’s fears and encourage him to perform his duty without being burdened by concerns of death or destruction. This teaching serves to bolster Arjuna’s courage and resolve.

Krishna emphasizes that the body is temporary, but the soul is eternal and cannot be destroyed. He advises Arjuna to view the body as a vessel that the soul temporarily inhabits. This understanding is meant to help Arjuna detach from his attachment to the physical forms of his loved ones and recognize the soul’s true, everlasting nature.

Krishna explains that the soul neither kills nor can it be killed, removing any moral dilemma associated with physical death. By this logic, killing in the battlefield affects only the body, not the soul. This insight is meant to release Arjuna from guilt and help him see beyond the physical consequences of his actions.
