There is something inside us always itchy to grow out of our bodies We did not know as we grew up We were obviously attracted by physical appearance to start with Then we grew with friends grew with books, movies, stories fictional or realistic Yet we still may not know in spiritual world what defines us apart from what physically demands us to fulfill in the daily world We might be too busy to learn knowledge or skills or learn what other people really are how to make more money to get more staff to get to more places but not enough time left to discover or explore ourselves But perhaps there is no pure separation between physical and spiritual world for a individual Perhaps it is like religion Not believing there is need or possibility for an independent spiritual world you don't have to look into it at all Happily thereafter in all ways Believing there is a pure spiritual world you will have a tendency to explore it further with your wings of the unfulfilled
