The supreme self is eternal, without a beginning (anadi), devoid of attributes or qualities (nirguna), and imperishable (avyaya). Despite residing within the physical body, the supreme self remains untouched by any actions performed by the body or the mind and is unaffected by any impurities. Krishna's teachings in this verse emphasize the transcendental nature of the supreme self. Unlike the physical body, which undergoes birth, growth, decay, and death, the supreme self is eternal and immutable. It exists beyond the realm of time and space, beyond the limitations of material existence.

The term "nirguna" indicates that the supreme self is beyond the realm of qualities or attributes. It is neither defined nor limited by any characteristics, such as form, colour, or sound. This attributeless nature of the supreme self signifies its absolute transcendence and universality.

Moreover, Krishna assures Arjuna that despite residing within the physical body, the supreme self remains unaffected by the actions or experiences of the body and mind. It neither engages in any activities nor undergoes any changes. This illustrates the supreme self's state of absolute detachment and non-attachment to the material world.

Krishna addresses Arjuna as "Kaunteya," emphasizing their familial relationship and guiding him with compassion and understanding. Through this verse, Krishna invites Arjuna to recognize the eternal and immutable nature of the supreme self, inspiring him to transcend the limitations of the material world and realize his own divine essence.

In essence, this verse underscores the fundamental principle of Advaita Vedanta, which teaches the non-dual nature of reality. It elucidates the concept of the supreme self as the ultimate reality, beyond the realm of dualities and distinctions. By understanding the eternal, attributeless, and imperishable nature of the supreme self, one can attain true liberation (moksha) and realize the eternal bliss of self-realization.
