"Do not lust (want) for it gives way to the desire to possess and the desire to possess incites murder." Buddhist saying
I see the word want as meaning dissatisfaction and the word murder as referring to the frustration, envy, greed, anger etc... a dissatisfied state of being can incite.
Life's lesson is one of letting go.
Have no fixed plan
Just this moment
But what is given
"Let all go dear
so comes love" e.e cummings
