By giving our power away to physicality we sacrifice a part of our spirit (Neptune) to the material world (Saturn), this is where we over-strategize and overindulge materially without regard for spirit. 

By giving our power away to the ideal (Neptune) we lose sight of practical requirements necessary to efficient functioning in physical reality. Both planets reflect the illusion of dis-empowerment. 

Better said you become too materialistic you lose your soul you become too spiritual the bills don't get paid.
