Acharya Prashant explains that the moment an individual becomes ready to improve themselves, they gain hope that the world can also improve. He suggests that those who claim the world or others cannot change are actually reflecting their own internal stagnation. When a person begins to experience purity and innocence, they naturally desire to share that state with everyone else, leading to a sense of faith that transcends mere hope. This transformation is the essence of spiritual practice, though it is often obstructed by bodily identification.
