Do not covet is fine to say. Certainly, it is good advice. But it misses the issue. Only from sense of lack does covetousness arise.

When sense of lack is replaced with awareness of plenty, covetousness is replaced with generosity. Needing and giving are but two sides of the same coin. You may need to be instructed in awareness of the wealth that is yours.

Who would grab when he sees there is enough to go around? When he sees abundance spilling over, what would he feel denied about? What would he possibly want to draw to himself and not to another?
