Kṛṣṇa explains the origin of social divisions (Varṇas). He says that the duties of intellectuals, warriors, businessmen, and workers are divided not by birth, but by ‘Svabhāva-prabhavair guṇaiḥ’—the qualities born of their own inherent nature and the modes of nature they associate with. It is a system based on aptitude and character, not on family names. This is a ‘Scientific’ social order. Just as a human body needs a head (thinking), arms (protecting), a stomach (digesting/wealth), and legs (supporting), a healthy society needs these four groups to function. Kṛṣṇa is telling Arjuna that everyone has a ‘natural frequency’. When we work according to our natural frequency, we are efficient and happy. When we try to imitate someone else’s role, we create chaos for ourselves and the world. It teaches us to ‘Know Our Nature’. We should find the work that matches our internal ‘Guṇa’. If you are naturally a thinker, be a teacher. If you are naturally a protector, be a leader. There is no ‘High’ or ‘Low’ in this system; every part of the body is essential. By embracing our own ‘Svabhāva’, we stop the stress of comparison and start the journey of perfection through our specific work. We are all unique parts of the Lord’s cosmic machine.
