Acharya Prashant explores the relationship between sorrow, time, and thought, referencing J. Krishnamurti's assertion that understanding sorrow requires understanding time and thought. He defines the ego as the thought of "I am X, now," emphasizing that 'now' is the very center of the ego in the realm of the mind, just as the body is the center of the ego in space. This 'now' is an arbitrary and personal location assigned within the stream of time, serving as the imaginary center from which the concepts of past and future are created. Without this personal 'now', the past and future cannot exist. He distinguishes between 'now' and the 'present', noting that 'now' is a personal and thought-based construct, whereas the present is all-encompassing. Time is identified as sorrow because it inherently involves endings and is fueled by thought. Acharya Prashant explains that the entire world is a thought centered on the body, and the entire future is a thought centered on the 'now'. Sorrow arises not from the existence of time itself, but from identifying with and becoming attached to the 'toys of time'—the stories of the past and the projections of the future. When the mind gives too much importance to these waves of time, it becomes heavy and loses its clarity.
