Acharya Prashant explains that certain popular spiritual books and teachings, such as those focusing on the concept of 'the power of now', can be beneficial as a starting point for individuals who are otherwise lost in dreams of the future. He acknowledges that for someone who reads nothing at all, such content provides a helpful beginning. However, he highlights a significant danger: the tendency of these authors and teachers to present limited, relative truths as if they were absolute, universal, and ultimate truths. He compares this to someone selling street food and claiming it is the most nutritious food available; while the food has its place, the claim of it being the ultimate health food is false and misleading.
