You are a new member. Welcome. This kind of sweeping statement is hard to understand. What is all encompassing knowledge? Do you have an example of what you gained by studying a story in Bhagavatha Purana. For example, there is a story of a demon who 'steals the vedas' to the bottom of ocean. From that story as an example, what insights can be gotten? How can veda (standing for knowledge) be stolen?Discussion and reading of Bhagwad Purana is recommended as it provides all encompassing knowledge.
