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 differentiates between the real and the unreal. The unreal, being temporary, will eventually perish, while the real, being eternal, never ceases to exist. This teaching helps Arjuna shift his focus from the perishable physical body to the indestructible soul, setting the stage for a deeper understanding of life and its true essence.

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 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.

The soul is never born, nor does it die. It is eternal, without beginning or end, and cannot be destroyed even when the body is slain. Krishna’s teaching aims to shift Arjuna’s perspective from the temporary nature of the body to the timelessness of the soul, allowing him to overcome his attachment and grief for those on the battlefield.

Understanding the eternal and unchangeable nature of the soul, one should not consider themselves as the killer or the killed. This teaching is meant to encourage Arjuna to look beyond physical actions and comprehend the soul’s imperishable essence, which cannot be harmed or destroyed by any external force, making him rise above fear and doubt.
