Kṛṣṇa explains the reality of our biological and psychological existence. No one can remain without performing some kind of action, even for a single moment. Even when you are sleeping or sitting still, your heart is beating, your lungs are breathing, and your mind is processing. Everyone is forced to act helplessly by the ‘guṇas’, or the modes of material nature (goodness, passion, and ignorance). These forces are like invisible strings that move the body and mind. We are not independent; we are part of a giant mechanical system that is always in motion. Since activity is unavoidable, the goal of yoga is not to stop it, but to master it. Trying to be ‘inactive’ is a fight against nature that you cannot win. Kṛṣṇa is telling Arjuna that since he *must* act, he should learn how to act in a way that leads to freedom rather than further bondage.
