Acharya Prashant explains that there is absolutely no difference between thinking (chintan) and action (karya), as thinking itself is a form of action. However, he clarifies that action cannot be equated merely with movement. If one moves around a lot but ends up back at the starting point, no real work has been done. He draws an analogy from physics, where work is defined as force multiplied by displacement. This concept applies not just to the physical world but also to the psychic, or inner, world. In the inner world, an action or thought is only considered 'work' if it involves a displacement of one's center. If your thinking leads to a displacement of your core self, then work has been accomplished. Otherwise, it is just fatigue, likened to the proverb, "Ate and drank nothing, but broke a glass worth twelve annas," signifying effort without result. Thinking that revolves around a fixed center without changing it is merely circular thought, and the work done is zero because there is no displacement. Therefore, thinking can be considered work only if it brings about a change in your center. This principle also applies to physical actions. A physical act, like moving an object, constitutes physical work. However, from an inner perspective, it is only considered true work if it leads to an internal displacement or progress. Many people work hard their entire lives, yet their inner world remains empty because their efforts are aimed at protecting their scared, inner center rather than changing or elevating it. For instance, a student might study hard out of fear of an exam, not out of love for the subject. This effort is to protect their existing state, not to transform it. Most of the world's hard work is driven by a desire to save oneself, not to elevate oneself. The real work, the true action, is to displace oneself from the dangerous position one is in, rather than trying to protect oneself while remaining in the same spot.
