Verse 8-16

आब्रह्मभुवनाल्लोका: पुनरावर्तिनोऽर्जुन |

मामुपेत्य तु कौन्तेय पुनर्जन्म न विद्यते || 16 ||

“From the highest abode of Brahma down to the lowest, all realms of existence are subject to rebirth, O Arjuna. But those who attain Me, O Kaunteya, do not have to take birth again.” 

Commentary: Lord Krishna explains that all beings, from the highest celestial realms down to the lowest material planes, are subject to the cycle of repeated births and deaths. Regardless of the specific realm or level of existence, every being experiences the process of reincarnation.

In the vast expanse of the universe, humanity occupies an insignificantly small portion. Below human realm, diverse species exist, each endowed with limited but specific abilities for adaptation. All species navigate survival and learning based on the unique environments they inhabit.

Remarkable examples abound in the animal kingdom, where species showcase extraordinary adaptations. Some animals possess the ability to perceive changes in their environment, while others navigate through sonar-based object detection. An intriguing case is the Mexican Axolotl, an aquatic salamander capable of regenerating multiple body parts, including limbs, heart, brain, and lungs. Similarly, the water bear exhibits resilience in extreme conditions, enduring high radiation, extreme temperatures, and even the vacuum of space.

While we are aware of these lower realms, the concept of higher regions of Brahma emerges from our recognition and acceptance of the complexity and limitations of our existence. Grappling with the dualities of life, faith in a mighty God and other divine beings provides solace. Although the highest divine abode remains beyond human comprehension, the cyclical nature of existence is still evident.

Lord Krishna emphasizes the significance of human birth and the need for making intelligent efforts for self-evolution. The verse serves as a reminder of the impermanence and transitory nature of worldly existence and highlights the importance of realizing one’s true nature.
