Acharya Prashant explains that knowledge, as described by Shri Krishna, is not the accumulation of sensual data or memory, but a purifier that reveals the limitations of worldly knowledge. While classical literature often describes knowledge as bondage, Shri Krishna refers to a real knowledge that arises from within, independent of the senses and the intellect. This inner knowing is spontaneous and causeless, unlike worldly knowledge which is external, dependent on reasons, and ultimately a source of doubt and insecurity. The yogi is one who lives by this inner guidance, rebelling against the tyranny of external systems and the conditioned self. True yoga is defined as a life of integrity and honesty where one's movements are dictated by the heart rather than the crowd. Acharya Prashant emphasizes that yoga is not a spiritual concept to be practiced in a corner, but a total way of living that leaves no room for compromise or dependence. It involves a state of inner certainty where one is no longer vulnerable to the world's influence. This state is achieved through self-annihilation rather than self-improvement, as the ego-self only seeks to decorate its own sickness. By surrendering completely to the truth, the yogi becomes one with the Lord, living in a dimension that is timeless and indestructible. To reach this state, one must stay close to their direct experiences without labeling or concluding them. Acharya Prashant suggests that naming an experience, such as hurt or love, is a way of escaping it and reinforcing the ego's false sense of knowing. By remaining vulnerable and observant of one's responses to the world, the fire of knowing can arise from the heart to purify the mind. Ultimately, yoga is the freedom from the container of the limited self, allowing one to discover their true nature as the infinite ocean of truth.
