Acharya Prashant interprets Kabir Saheb's couplet about the grinding stone, explaining that the two stones represent duality. He states that wherever there is duality, the world is being crushed like grains of wheat. Duality consists of opposites that appear different but always exist together and depend on each other, such as day and night, pleasure and pain, or success and failure. He emphasizes that the mind is the hub of this duality; anything one can think of has an opposite, and being caught between these opposites leads to suffering. He further explains that the true self is beyond thought and cannot be conceptualized because it exists outside the realm of duality. While one can know the self, it is a thoughtless knowing that cannot be felt or thought about in the conventional sense. He points out that people often seek pleasure, which inevitably brings pain, or even seek pain to derive pleasure, as seen in thrill-seeking or fasting. He argues that even grief over death is rooted in the ego and the loss of one's own identity rather than genuine compassion for the deceased. Finally, he discusses how the ego serves as the center of an individual's universe, shaping their perception of reality. He illustrates this by explaining that labels like terrorist or warrior depend entirely on one's perspective and identity. Our attachments and identities dictate how we view the world, and we only feel sorrow when our own interests or identities are threatened. He concludes that we see the world not as it is, but as we have conditioned ourselves to see it from our specific standpoint.
