About spiritiual knowledge

Furthermore, nowhere else are there such elaborate explanations of the spiritual world and what goes on there, or how we can truly enter that region, and what the areas are that surround the cosmic creation. Also, nowhere else can you find such detailed descriptions of how the universe was created. Often you will find in a scripture a simple allegory for people to believe that gives only the slightest ideas of how the worlds were created. But in the Vedic literature, there are complex explanations of how and when things took place in order to manifest the universe as we see it now. [Stephen Knapp's book, "How the Universe was Created," gives these details.]
For these reasons, anyone of any religion can study the Vedic scripture to add to whatever spiritual understanding they already have. Or if they don't have any spiritual understanding, then you just found the mother lode, the main vein of spiritual knowledge of which all others are but portions.
