Malchut in Netzach - ruling and being effective in eternity.
Long term effectiveness - how to put something in place that stands the test of time - I often worry so much I don't dip a toe into the water.
And shouldn't we worry? Someone once thought that eating fat made us fat, so eating low fat would make us skinny. And a person who sold sugar thought that was a great idea. Forty years later look at the experiment that has resulted in the American diet and our health.
We must be careful when we act with eternity in mind, and perhaps we should always act with eternity in mind. The long term effect of this action, and acting with a sense of the long term, these frameworks may be better starting points in any moment of decision and planning.
Act, be bold, and be thoughtful too!
