There is an old saying: spirit lives by giving, matter lives by taking. One interpretation: by sharing knowledge, your "possession" doesn't diminish, but grows as it lives in more minds; however when you share food, you have less food. This explains how the spirit's innate drive to grow becomes greed when it expresses itself thru matter. Only when it stops identifying with matter, it becomes free.
