Acharya Prashant explains that the fundamental difference between thoughts lies not in the act of thinking itself, but in the source from which those thoughts arise. He compares thought to a flow, noting that while both a pure river like the Ganga and a dirty drain are flows, their origins are vastly different. The Ganga originates from the pure, distilled waters of the Himalayas, whereas a drain originates from sewage and waste. Similarly, thoughts can arise from the source of Truth and the Self, or they can stem from illness and mental tendencies. He emphasizes that the thoughts of saints like Kabir Saheb and Raman Maharshi are rooted in awareness and meditation, serving as mere tools to resolve a situation before dissolving naturally.
